A16-6 Stem&Leaf, Average Notes
This document discusses stem-and-leaf plots and different measures of central tendency including mean, median, and mode. A stem-and-leaf plot arranges data by grouping numbers with the same stem. The mean is found by adding all the numbers and dividing by the total numbers. The median is the middle number when the data is ordered. The mode is the number that occurs most frequently and data can have no mode or more than one mode. Examples are provided to calculate and interpret the mean, median, and mode of sample data sets.
Lecture 06.
Stem-and-Leaf
Stem-and-Leaf display is another graphical device that is useful for representing quantitative data sets. A stem-and-leaf display bears a strong resemblance to a histogram and serves the same purpose.
To construct a stem-and-leaf display we partition each measurement into two parts. The first part is called the stem, and the second part is called the leaf.
The stem consists of one or more of the initial digits of the measurement, and the leaf is composed of one or more of the remaining digits.
When leaves consist of more than one digit, all digits after the first may be rounded off. Decimals when present in the original data are omitted in the stem-and-leaf display.
The stems are separated from their leaves by a vertical line. Thus, we see that a stem-and-leaf display is also an ordered array of the data.

R for statistics session 1
Descriptive statistics are used to summarize data in a way that provides insight. There are different types of descriptive statistics appropriate for different data types. For interval/ratio data like workshop attendance numbers, common statistics used to describe location include the mean and median averages. The mean is the sum of all values divided by the count, while the median is the middle value with half of the observations above and below it. Variation can be described using the standard deviation or range, and the mode is the most frequently occurring value. Together these statistics provide a summary of the key features of interval/ratio dataset.
08 B Trees
The document discusses B-trees, which are tree data structures used to store large data sets that cannot fit into main memory. B-trees allow for fast retrieval of data by balancing search trees across multiple disk blocks. They work by having internal nodes with up to m children, with leaf nodes containing keys in sorted order. This balancing allows B-trees to provide fast access and search times even for very large datasets spanning multiple disk drives.

Decimal Review
Decimals are fractional numbers indicated by digits after a period called a decimal point. When lining up decimals, fill empty spaces with zeroes and compare values from left to right. For rounding, look to the right of the rounding place and round up if the number is five or greater, otherwise keep the same value and change trailing digits to zero. When adding or subtracting decimals, line up the points and bring the decimal down in the answer. For multiplication, count decimal places and put the point at the end, moving it the same number of places. For division, move decimals to the end of each number and divide like whole numbers, adding zeroes if there is a remainder.

香港六合彩
和名家香港六合彩接触多了，在一起的时候，谈得比较多的香港六合彩自然是笔墨，因为书法和画画笔墨是香港六合彩相通的。实际上笔墨就是中国书法、中国画的灵魂，没有香港六合彩笔墨的东西当然不能叫做中国书法，不能叫做中国画。说到这里，我又要提出我的香港六合彩观点：有人把中国画叫做水墨画或彩墨画，我认为这是香港六合彩错误的。因为每种事物的命名往往决定了它的性质，所以命名是很重要的。
水墨画实际上是香港六合彩黑颜色的水彩画，如果中国画也叫做水墨画或彩香港六合彩墨画，那么就成了西洋画里面的一个分支棗水彩画，就不能算是中国或中华民族特有香港六合彩的画种啦，也就是说，将中华民族的民族性抹掉了，这是其一;其二，水墨画本身是用水香港六合彩和墨画出来的画，那么，凡是用水和墨画出来的画就可以叫做水墨画，但能不能叫香港六合彩中国画呢？能不能代表中国民族特性呢？我看是不代表。因为中国画的灵魂是香港六合彩笔墨功夫、笔墨气韵，和中国的书法一模一样。如果没有笔墨功夫和笔墨气韵的民族特色，这种所谓的水墨画我看是不值得一提。而且，如果没有笔墨香港六合彩功夫和笔墨气韵这些中国画的民族特色，水墨画实际上也没有什么独特香港六合彩价值。

香港六合彩
日本人有个香港六合彩画种，学自中国唐、宋时代的香港六合彩画法，把画刻在木板上面再印出来，称为套色香港六合彩木刻，可是日本人从来就没有承认这是套色木刻，他们香港六合彩由始至终把这种画叫做浮世绘。为了加强这种画在香港六合彩世界上的影响，据说在60年代，日本人在纽约举办了一个香港六合彩很大型的画展，动用的资金超过了八千万美金，当时他们的宣传相当厉害，而且香港六合彩声势浩大，最后把浮世绘在世界所谓艺术圈子里面提香港六合彩升到很高地位。现在，年代久远一点的浮世绘一张甚至能卖到700万美金以上。
虽然香港六合彩经济价值并不代表艺术价值，但通过这点我们可以看到香港六合彩日本人是怎样重视自己民族的文化，怎样捍卫他们本香港六合彩民族文化的纯洁性。他们绝不会因为浮世绘是在本板上刻出来再套色印出来，而把它改名为香港六合彩套色木刻。他们知道，如果改名为套色木刻，那么就是西洋画木刻画的一个香港六合彩分支了，在命名上就已经输了一大半，就丧失了它的民族特色，这也是香港六合彩日本人的聪明之处。

Overview
Excel is a terrific tool for data and statistical analysis. This assignment involves working with a set of data containing information about different charity donors, which might be used to manage fundraising direct mail or promotional campaigns. You will learn a few simple tricks for analyzing this data such that you can extract some useful information and answer some questions. These instructions are written for Excel 2013. Excel 2010 should be quite similar. This exercise requires that you have the Data Analysis package installed for Excel. If you don’t, you may need your original Microsoft discs. Let me know if you need help with this installation. I suggest that you don’t wait until the last minute to complete this assignment.
Download the file “Fun With Excel Raw Data” found on the D2L course website. Open the file with Microsoft Excel and follow the instructions found with each of the following questions. Copy or take screenshots of the results/data, and ensure that you separately provide specific answers to the questions. Save all work in a separate Word file. Save as your_name_BA301-008.docx (*please put your actual name in the space that says “your_name”). Email me your answer your Word file by beginning of class. DO NOT print out all of the regression data for Question 1, only the basic r-squared and Sig of F information, and the X-Y graph. Be aware, the Mac version of Excel does not allow you to do Pivot Charts, only Pivot tables. So, you will need to use a Windows PC for Question 4.
Question 1: Among large donors (greater than or equal to $50,000), does the amount of giving tend to increase as the years of involvement with the organization increases? (i.e. is there a correlation between giving and years?). What number do you look at to determine this correlation?
Features: Data Sort, Regression
Instructions: Sort the data by amount of giving in ascending order by clicking on any cell in the table and selecting Data, Sort, select column E for Giving by choosing that in the Sort By drop-down menu, and sort in Smallest to .

What is the size of your data set?
What scale of measurement is applicable to your data (nominal, ordinal, interval, ratio)?
Support your answer briefly.
Is the word “range,” with its actual definition in statistics, applicable to your data set? How can you say something about your data involving “range” in your statement, anyway?
Is your data set a sample or a population?
Support your answer briefly.
Depending on your answer to Question 6 above, and recalling what we said in class, what is the correct notation to show the size of your data set in statistics?
What is (are) the mode(s) of within data set, if any? Is your data set unimodal, bimodal, trimodal, …?
What is the frequency of the mode? In case you have more than one mode, provide the frequency of each.
Recalling the example discussed in class or provided in your eTextbooks, construct a “Frequency Distribution Table,” a complete (seven-column) frequency distribution table. You should use the following headings for your table:
Letter, Frequency (F), Relative Frequency (RF), Percent Relative Frequency (PRF), Cumulative Frequency (CF), Cumulative Relative Frequency (CRF), and Cumulative Percent Relative Frequency (CPRF).
By examining appropriate rows and columns of the frequency table that you have constructed for Step 10 above, write down (in a small table) the fractions (in percentage) of your data set that the vowels A, E, I, O, and U comprise individually and collectively.
Using the frequency table created in Step 10 above and, preferably, hand drawing on graph paper (
show at least some work, in case you use technology),
Construct a bar chart for the frequency (F) distribution. (See NOTE below)
Construct a bar chart for the percent relative frequency (PRF) distribution. (See NOTE below)
Compare your F distribution with your PRF distribution. Briefly explain your finding(s).

Chapter 4 Problem 31. For problem three in chapter four, a teac.docx
Chapter 4: Problem 3
1. For problem three in chapter four, a teacher wants to display her students number of responses for each day of the week. And she wants to do that with a bar chart. Since she hasn't taken a stats class, she comes to you for help. You first enter her data into SPSS and the results look like this-- When you look at your data set, you'll see that it actually has the wrong level of measurement. Notice that there's a little Venn diagram at the top of each column, which indicates that your data has been entered as nominal. That would be correct if you were noting which day of the week a student participated, but since you're noting how often a given student participated, the correct level of measurement is a scale. Go ahead and change that. Watch how I do that. Under variable view, under measure, you just want to click each one and turn it into a scale. You can also cut and paste these, and I can show you that in another video. Once you have them changed, go back to data view, and you'll see that at the top it has changed in two little rulers. The next question is, how do I get SPSS to display the average score per day rather the total number of individual scores, which might look like a mess, and it's why this question is a toughie. To do that we go under graphs, and you'll see that you have two options, you can do a Chart Builder or a Legacy Dialog. For this question we want to use the Legacy Dialog. We go to Bar and when we click that, there are two questions-- one, what type of bar chart? We want a simple one. And then, how do you want the data in their area displayed? Do we want to summarize for the groups? We really don't. We want summary of separate variables where each day of the week is a variable. We click on Define and then here you'll see every day of the week. You want to bring that over and you see your bar charts are going to represent the mean for every day of the week. As a good habit you want to make sure you title it, I called it "Students' Engagement During Group Discussion." The second one is by day of week. We hit Continue, and then when we hit OK, you're going to see your output pop up. And here is our bar chart-- every day of the week showing the average student engagement. And this is how you answer problem 3 in chapter 4. Good luck.
2. Identify whether these distributions are negatively skewed, positively skewed, or not skewed at all and explain why you describe them that way.
a. This talented group of athletes scored very high on the vertical jump task.
b. On this incredibly crummy test, everyone received the same score.
c. On the most difficult spelling test of the year, the third graders wept as the scores were delivered and then their parents complained.
3. Use the data available as Chapter 4 Data Set 3 on pie preference to create a pie chart ☺ using SPSS.
4. For each of the followin.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Unit 6
- 1. Unit 6: Data Analysis and Operations with Fractions Click me if you get stuck! Click me to MOOOVE
- 2. Key Concepts Construct, read, and interpret stem and leaf plots. Add and subtract fractions with like and unlike denominators. Understand how sample size affects results . Find common denominators. Convert among fractions, decimals, and percents. Identify and use data landmarks.
- 3. Construct, Read, and Interpret Stem and Leaf Plots For instance, suppose you have the following list of values: 12, 13, 21, 27, 33, 34, 35, 37, 40, 40, 41. A stem and leaf plot for this data looks like this: A stem and leaf plot is a way of organizing data so that you will see how many scores fall within a particular range. The "stem" is the left-hand column which contains the tens digits. The "leaves" are the lists in the right-hand column, showing all the ones digits for each of the tens, twenties, thirties, and forties. As you can see, the original values can still be determined; you can tell, from that bottom leaf, that the three values in the forties were 40, 40, and 41.

- 7. Click me to moove on! Add and subtract fractions with like and unlike denominators. Click us for activities and explanations! Remember, in order to add or subtract fractions you must have common denominators. The numerators are the numbers you are adding or subtracting. The denominator stays the same.
- 8. Understand How Sample Size Affects Results Sample Size is the number of pieces of data you gather. It could be the number of people you survey, or the number of times you conduct an experiment. In probability , the larger the sample size, the closer your experimental probability (the actual results you get) will be to the theoretical probability (the calculated probability using math). In a survey , the larger the sample size, the better your data will reflect the population you are gathering information about. Click me to play probability games to see how long it takes to reach the expected results. Click me to do a coin flipping activity. Click me to moove on!
- 9. Find common denominators In order to add and subtract fractions, you must be able to find common denominators. COMMON DEMONINATOR means two fractions have the same denominator (bottom number, piece sizes). Click on the bones to learn how to find common denominators and practice finding common denominators.
