The document discusses using score distribution analysis to help recruiters quickly evaluate how well candidates fit a role. It describes calculating the mean, standard deviation, and bell curve of scores to analyze where candidates fall relative to the average. A low standard deviation means scores are close to the average, while a high value means more variation. An example calculates the mean of 76 and standard deviation of 14.53 for 5 candidates' test scores to benchmark them against the average.

The standard normal curve & its application in biomedical sciences
1) The document discusses the normal distribution and its applications in statistical inference. It is the most important probability distribution used to model many continuous variables in biomedical fields.
2) The normal distribution is characterized by its mean and standard deviation. It is perfectly symmetrical and bell-shaped. Properties of the normal curve include that about 68%, 95%, and 99.7% of the data lies within 1, 2, and 3 standard deviations of the mean, respectively.
3) The standard normal distribution is used to convert raw scores to z-scores in order to compare variables measured on different scales. Z-scores indicate how many standard deviations a score is above or below the mean and can be used to determine probabilities, percentiles
Standard deviation (3)
The document discusses how to calculate variance and standard deviation. It provides the formulas and steps to find variance as the average squared deviation from the mean. Standard deviation is defined as the square root of variance and measures how dispersed data are from the mean, with a larger standard deviation indicating more variation. Examples are worked through to demonstrate calculating variance and standard deviation for different data sets.
Week 7 lecture_math_221_dec_2012
This document discusses normal distributions and how to calculate probabilities and confidence intervals related to normal distributions using Minitab software. Key topics covered include the standard normal distribution, using Minitab to calculate normal distribution probabilities, examples of finding z-scores and areas under the normal curve, confidence intervals for means and proportions, and interpreting confidence intervals.
Derived Scores
1) Derived scores help interpret raw scores and make them comparable by expressing them in terms of standard deviations from the mean.
2) There are two main types of derived scores - standard scores (z-scores) which indicate how many standard deviations a score is from the mean, and percentile ranks which show the percentage of scores in the group that are the same or lower.
3) Z-scores are calculated using the formula z = (x - M) / SD, where x is the raw score, M is the mean, and SD is the standard deviation. This expresses how many standard deviations a score is from the mean.

Week 7 lecture_math_221_apr_2012
The document provides an overview of the standard normal distribution and how to calculate probabilities and find z-scores, confidence intervals, and proportions using the normal distribution in Minitab. Examples are presented on finding probabilities based on z-scores, determining if a sample value falls within a certain percentage, calculating confidence intervals for means and proportions, and interpreting what confidence intervals represent.
Standard Scores
Z-scores, also called standard scores, measure how many standard deviations a raw score is above or below the mean of its distribution. A z-score indicates where a particular score lies in relation to all other scores in the distribution. To calculate a z-score, the raw score is subtracted from the mean and divided by the standard deviation of the distribution. Z-scores can be positive, negative, or zero, depending on whether the raw score is above, below, or equal to the mean. Several examples are provided to demonstrate calculating z-scores from raw scores, means, and standard deviations.

21.12.14 descriptive statistic
This document discusses descriptive statistics and their uses in research. Descriptive statistics describe basic features of data through simple summaries, and allow researchers to describe many data points with a few key values. These include distributions to show frequencies of values, measures of central tendency like mean, median and mode, and measures of dispersion like range and standard deviation. The mean is the average value and is calculated by summing all values and dividing by the number of values. The median is the middle value when values are arranged in order. The mode is the most frequent value. Standard deviation measures how spread out values are from the mean.
Employee Termination
1. The document discusses building a random forest model to predict employee attrition and identify key drivers of attrition.
2. The model found promotion, tenure, time in last position, annual income, and year of birth to be the most important predictors of attrition.
3. The model is used to segment employees into high, medium, and low risk profiles for attrition and establish thresholds for key drivers like tenure and job level.
Measures of Dispersion
If everything were the same, we would have no need of statistics. But, people's heights, ages, etc., do vary. We often need to measure the extent to which scores in a dataset differ from each other. Such a measure is called the dispersion of a distribution.
QT1 - 07 - Estimation
The document discusses estimation and different types of estimates used to estimate population parameters based on sample data. Point estimates provide a single value while interval estimates provide a range of values. Good estimators are unbiased, efficient, and consistent. Common point estimators are the sample mean and sample standard deviation. Interval estimates use the point estimate plus/minus a margin of error calculated from the standard error. Confidence intervals provide a probability that the population parameter lies within the interval estimate.
Statistics101: Numerical Measures
This document discusses key concepts in descriptive statistics including measures of central tendency (mean, median, mode), variability (range, variance, standard deviation), the normal distribution, z-scores, and the relationship between variables (covariance and correlation). It provides examples and formulas for calculating these common statistical measures and explains how to interpret them. Skewness is also introduced as a measure of the symmetry of a dataset.
Measures of dispersions
1. The document discusses various measures of dispersion used to quantify how spread out or variable a data set is. It describes measures such as range, mean deviation, variance, and standard deviation.
2. It also discusses relative measures of dispersion like the coefficient of variation, which allows comparison of variability between data sets with different units or averages. The coefficient of variation expresses variability as a percentage of the mean.
3. Additional concepts covered include skewness, which refers to the asymmetry of a distribution, and kurtosis, which measures the peakedness of a distribution compared to a normal distribution. Positive or negative skewness and leptokurtic, mesokurtic, or platykurtic k

measure of variability (windri). In research include example
This document discusses various measures of variability that can be used to describe how spread out a distribution is. It describes four major measures: range, quartile deviation, average deviation, and standard deviation. The range is the simplest measure, being the difference between the highest and lowest values. The quartile deviation uses the interquartile range to describe the middle 50% of scores. The average deviation takes the average of all deviations from the mean. The standard deviation is the most common measure, being the positive square root of the variance, which is the average of the squared deviations from the mean. Examples are provided for calculating each measure using both grouped and ungrouped data.

Confidence Interval Module
One of the key concepts of statistics enabling statisticians to make incredibly accurate predictions is called the Central Limit Theorem. The Central Limit Theorem is defined in this way:
· For samples of a sufficiently large size, the real distribution of means is almost always approximately normal.
· The distribution of means gets closer and closer to normal as the sample size gets larger and larger, regardless of what the original variable looks like (positively or negatively skewed).
· In other words, the original variable does not have to be normally distributed.
· This is because, if we as eccentric researchers, drew an almost infinite number of random samples from a single population (such as the student body of NMSU), the means calculated from the many samples of that population will be normally distributed and the mean calculated from all of those samples would be a very close approximation to the true population mean. It is this very characteristic that makes it possible for us, using sound probability based sampling techniques, to make highly accurate statements about characteristics of a population based upon the statistics calculated on a sample drawn from that population.
· Furthermore, we can calculate a statistic known as the standard error of the mean (abbreviated s.e.) that describes the variability of the distribution of all possible sample means in the sa ...

Standard deviation & variance
The document discusses standard deviation and variance. It defines standard deviation as a measure of how spread out numbers are from the average. A low standard deviation means the numbers are close to the average, while a high one means they are more spread out. The document provides formulas for calculating variance using summation notation and standard deviation as the square root of variance. It includes an example of calculating standard deviation from a set of test scores.
Topic 8a Basic Statistics
This document discusses various statistical measures used to summarize and describe data, including measures of central tendency (mean, median, mode) and measures of dispersion (range, variance, standard deviation). It provides definitions and examples of calculating each measure. Standardized scores like z-scores and t-scores are also introduced as ways to compare performance across different tests or distributions. Exercises are included for readers to practice calculating and interpreting these common descriptive statistics.
Normal distribution
This document discusses the normal distribution and how to standardize data. It explains that normally distributed data forms a bell curve around a central mean. It also describes how the standard deviation measures how spread out data is, with 68% of values within 1 standard deviation of the mean, 95% within 2 standard deviations, and 99.7% within 3 standard deviations. The document demonstrates how to convert a value into a z-score or standard score by subtracting the mean and dividing by the standard deviation, effectively standardizing the data.
m2_2_variation_z_scores.pptx
This document provides an overview of standard deviation and z-scores. It begins by listing the key learning objectives which are to describe the importance of variation in distributions, understand how to calculate standard deviation, describe what a z-score is and how to calculate them, and learn the Greek letters for mean and standard deviation. It then provides explanations and examples of how to calculate and interpret standard deviation as a measure of variation, how to convert values to z-scores based on the mean and standard deviation, and the importance of ensuring distributions are normal before using these statistical techniques. It emphasizes understanding the concepts rather than just memorizing formulas.

Standard deviation quartile deviation
This document discusses measures of dispersion, specifically standard deviation and quartile deviation. It defines standard deviation as a measure of how closely values are clustered around the mean. Standard deviation is calculated by taking the square root of the average of the squared deviations from the mean. Quartile deviation is defined as half the difference between the third quartile (Q3) and first quartile (Q1), which divide a data set into four equal parts. The document provides examples of calculating standard deviation and quartile deviation for both individual and grouped data sets. It also discusses the merits, demerits, and uses of these statistical measures.
Measures-of-Central-Tendency.ppt
This document discusses various measures of central tendency including the mean, median, and mode. It provides examples of how to calculate each measure using both raw data sets and frequency distributions. The mean is calculated by adding all values and dividing by the total number of cases. The median is the middle value when cases are arranged in order. The mode is the most frequent value. Limitations of each measure are also outlined, such as the mean being affected by outliers and the median requiring ordered data.

3) Formulas are given for calculating the mean, variance, and standard deviation of discrete random variables from their probability mass functions.
Standard deviation & variance
The document discusses standard deviation and variance. It defines standard deviation as a measure of how spread out numbers are from the average. A low standard deviation means the numbers are close to the average, while a high one means they are more spread out. The document provides formulas for calculating variance using summation notation and standard deviation as the square root of variance. It includes an example of calculating standard deviation from a set of test scores.
Topic 8a Basic Statistics
This document discusses various statistical measures used to summarize and describe data, including measures of central tendency (mean, median, mode) and measures of dispersion (range, variance, standard deviation). It provides definitions and examples of calculating each measure. Standardized scores like z-scores and t-scores are also introduced as ways to compare performance across different tests or distributions. Exercises are included for readers to practice calculating and interpreting these common descriptive statistics.
Normal distribution
This document discusses the normal distribution and how to standardize data. It explains that normally distributed data forms a bell curve around a central mean. It also describes how the standard deviation measures how spread out data is, with 68% of values within 1 standard deviation of the mean, 95% within 2 standard deviations, and 99.7% within 3 standard deviations. The document demonstrates how to convert a value into a z-score or standard score by subtracting the mean and dividing by the standard deviation, effectively standardizing the data.
m2_2_variation_z_scores.pptx
This document provides an overview of standard deviation and z-scores. It begins by listing the key learning objectives which are to describe the importance of variation in distributions, understand how to calculate standard deviation, describe what a z-score is and how to calculate them, and learn the Greek letters for mean and standard deviation. It then provides explanations and examples of how to calculate and interpret standard deviation as a measure of variation, how to convert values to z-scores based on the mean and standard deviation, and the importance of ensuring distributions are normal before using these statistical techniques. It emphasizes understanding the concepts rather than just memorizing formulas.
Variability, the normal distribution and converted scores
Understanding mean and standard deviation in the normal distribution curve, Understanding scores using range, semi-interquartile range, standard deviation and variance. Converting scores through z- scores and t - scores,
Standard deviation quartile deviation
This document discusses measures of dispersion, specifically standard deviation and quartile deviation. It defines standard deviation as a measure of how closely values are clustered around the mean. Standard deviation is calculated by taking the square root of the average of the squared deviations from the mean. Quartile deviation is defined as half the difference between the third quartile (Q3) and first quartile (Q1), which divide a data set into four equal parts. The document provides examples of calculating standard deviation and quartile deviation for both individual and grouped data sets. It also discusses the merits, demerits, and uses of these statistical measures.
Measures-of-Central-Tendency.ppt
This document discusses various measures of central tendency including the mean, median, and mode. It provides examples of how to calculate each measure using both raw data sets and frequency distributions. The mean is calculated by adding all values and dividing by the total number of cases. The median is the middle value when cases are arranged in order. The mode is the most frequent value. Limitations of each measure are also outlined, such as the mean being affected by outliers and the median requiring ordered data.

Interview Mocha's Score Distribution Analysis
- 2. Why is the score distribution analysis done? › Recruiters shouldn’t have to flip between the job description and a candidate’s score report to identify how well the candidate fits the role. › At a glance, a recruiter should be able to quickly identify if a candidate’s score falls within the “acceptable fit or average” zone of the scale. Ergo, Mocha’s score distribution analysis does the job!
- 3. Identify the candidate amongst average score via › Standard Deviation › Mean › Bell Curve
- 4. Standard Deviation (SD) SD is used to indicate how many candidates are spread out in relation to the average(mean) score. › A low SD value close to 0, indicates candidates close to average score. › A high SD value is spread out, away from the average score.
- 5. View the percentage of candidates in the range close to the average value (here: 0)
- 6. Using the standard deviation formula, we can calculate high and low SD values Sum of Mean Number of candidates
- 7. Example Candidates Test scores James 92 Lilian 88 Victor 80 Jordon 68 Jamie 52 › Test – General Aptitude › Appeared candidates - 5 › Test score - 100
- 8. 1. Find the mean: (92+88+80+68+52)/5 = 76 Mean (x) = 76 2. Find the deviation from the mean: 92-76 = 16 88-76 = 12 80-76 = 04 68-76 = -8 52-76 = -24
- 9. 3. Square the deviation from the mean: (16)^2 = 256 (12)^2 = 144 (04)^2 = 16 (-8)^2 = 64 (-24)^2 = 576 4. Find the sum of the squares of the deviation from the mean: 256+144+16+64+576 = 1056
- 10. 5. Divide the number of total candidates to find the variance: 1056/5 = 211.2 6. Find the square root of the variance: Thus the Standard deviation of the test score is 14.53 and mean is 76
- 11. Therefore, to Benchmark the candidate with respect to the average score, we display the analysis in the form of a Bell curve. The standard deviation slots will be in the range of 14.53 above and below the mean/average score of 76. e.g. A candidate named Greg scoring 65 will be seen among 68% of the bulk scoring close to the average marks.
- 12. THANK YOU!
