Inferential statistics uses analytical tools to draw conclusions about populations from samples. Some common inferential statistics tests include the t-test, which compares means between two groups; correlation coefficients, which measure the strength and direction of relationships between variables; analysis of variance (ANOVA) tests, which compare means across multiple categorical groups; and chi-square tests, which measure how observed data matches a theoretical model. Researchers preset a level of significance, such as 0.01 or 0.05, to determine whether results reject the null hypothesis and are statistically significant.

What are parametric and nonparametric inferential tests?
Solution
Inferential statistics suggest statements about a population based on a sample from that
population. Parametric inferential tests are carried out on data that follow certain parameters: the
data will be normal (i.e. the distribution parallels the bell curve); numbers can be added,
subtracted, multiplied and divided; variances are equal when comparing two or more groups; and
the sample should be large and randomly selected.
There are generally more statistical technique options for the analysis of parametric than non-
parametric data, and parametric statistics are considered to be the more powerful. Common
examples of parametric tests are: correlated t-tests and the Pearson r correlation coefficient.
Inferential statistics suggest statements or make predictions about a population based on a
sample from that population. Non-parametric tests relate to data that are flexible and do not
follow a normal distribution.
They are also known as.
Parametric tests

Statistical data handling
Statistics is an important tool in pharmacological research that is used to summarize (descriptive statistics) experimental data in terms of central tendency (mean or median) and variance (standard deviation, standard error of the mean, confidence interval or range)
t-test vs ANOVA
T-test and ANOVA are statistical techniques used to test hypotheses and compare population means. The t-test is used to compare the means of two samples or groups, while ANOVA can compare the means of more than two groups. Specifically, the t-test examines whether two sample means are significantly different and assumes a normal distribution and unknown standard deviation. ANOVA compares three or more population means by assessing variation within and between groups, and assumes samples are from normally distributed populations with equal variances. Researchers should use a t-test when comparing only two means and ANOVA when comparing more than two means to avoid increasing the chances of a Type I error.
Common Statistical tools and guides test
This document provides an overview of common statistical tools used for descriptive statistics, inferential statistics, regression analysis, correlation analysis, probability distributions, and sampling techniques. Descriptive statistics summarize and present data through measures like mean, median, mode, and standard deviation. Inferential statistics allow researchers to make generalizations about populations based on samples using techniques like t-tests, ANOVA, and chi-square tests. Regression analysis and correlation analysis examine relationships between variables. Probability distributions assign probabilities to possible outcomes, and sampling techniques select subsets from populations.
Common Statistical Tests.pdf
Common statistical tests can be used for correlation, comparison of means, regression, or non-parametric analysis. Correlational tests measure the strength of association between variables, comparison of means tests examine differences between group averages, regression assesses how one variable predicts another, and non-parametric tests are used when data does not meet assumptions for standard tests. Specific tests mentioned include the Pearson, Spearman, and chi-square for correlation, paired t-test, independent t-test and ANOVA for means, simple and multiple regression, and the Wilcoxon rank-sum, Wilcoxon sign-rank, and sign tests for non-parametric analysis.

The chi-square test is used to determine if there is a significant association between two categorical variables. It can be used for independence tests between two variables or goodness-of-fit tests to determine if observed data fits a theoretical distribution. The chi-square test calculates expected frequencies and compares them to observed frequencies to determine if any differences could be due to chance or indicate a true association. It is widely applied in research fields to analyze relationships in categorical data.9_Different_Statistical_Techniques.pptx

Application of-different-statistical-tests-in-fisheries-science
1. Statistical tests are used in fisheries science to test hypotheses and make quantitative decisions about fisheries processes. Common statistical tests include correlation tests, comparison of means tests, regression analyses, and hypothesis tests.
2. The appropriate statistical test to use depends on the research design, data distribution, and variable type. Parametric tests are used for normally distributed data, while non-parametric tests are used when assumptions are not met.
3. Accuracy of statistical tests relies on quality survey data. Both fishery-dependent and fishery-independent data are important, though confounding factors must be considered with dependent data. Proper study design and use of statistics allows prediction of fish production.

Parametric vs non parametric test
Parametric and non-parametric tests differ in their assumptions about the population from which data is drawn. Parametric tests assume the population is normally distributed and variables are measured on an interval scale, while non-parametric tests make fewer assumptions. Examples of parametric tests include t-tests and ANOVA, while non-parametric examples include chi-square, Mann-Whitney U, and Wilcoxon signed-rank. Parametric tests are more powerful but rely on stronger assumptions, while non-parametric tests are more flexible but less powerful. Researchers must consider the characteristics of their data and questions being asked to determine the appropriate test.
Artificial Intelligence (Unit - 8).pdf
Regression analysis is a statistical method used to determine the relationship between a dependent (target) variable and one or more independent (predictor) variables. It builds a model to best predict the value of the dependent variable based on the independent variables. Simple linear regression involves one independent variable, finding the best fit line that minimizes the error between predicted and actual dependent variable values. The regression coefficient indicates the strength and direction of the linear relationship between the variables. While correlation demonstrates association, regression can be used to predict future behavior based on the linear model.

The sequence is defined by the rule Fn=Fn-1+Fn-2, with terms numbered from 0 and the next terms found by adding the two numbers before it, creating the sequence 0, 1, 1, 2, 3, 5, 8, etc. When plotted geometrically by making squares with widths of successive Fibonacci numbers, the squares form a spiral shape.
Logic.pdf
Logic is the science and art of correct thinking. Aristotle is regarded as the father of logic. A proposition or statement is a declarative sentence that is either true or false. George Boole introduced symbolic logic using symbols like conjunction, disjunction and negation. Truth tables show the truth values of compound statements based on the truth values of simple statements. Logic puzzles can be solved through deductive reasoning. Kenken puzzles involve filling a grid with numbers according to arithmetic operations and non-repeating digits. Magic squares are grids filled with numbers such that all rows, columns and diagonals have the same sum.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Inferential statistics.pdf
- 1. Inferential statistics ➢ is a branch of statistics that makes the use of various analytical tools to draw inferences about the population data from sample data. T-test: ➢ is a statistical test that is used to compare the means of two groups. It is often used in hypothesis testing to determine whether a process or treatment actually has an effect on the population of interest, or whether two groups are different from one another. Correlation coefficient : ➢ is a statistical measure of the strength of a linear relationship between two variables. • The Pearson correlation coefficient (r) is the most common way of measuring a linear correlation. It is a number between –1 and 1 that measures the strength and direction of the relationship between two variables. • The Spearman correlation between two variables is equal to the Pearson correlation between the rank values of those two variables; while Pearson's correlation assesses linear relationships. Analysis of Variance(ANOVA): ➢ An ANOVA test is a type of statistical test used to determine if there is a statistically significant difference between two or more categorical groups by testing for differences of means using variance. CHI – Square: ➢ chi-square (χ2 ) statistic is a test that measures how a model compares to actual observed data. Level of Significance: ➢ The level of significance is stated to be the probability of type I error and is preset by the researcher with the outcomes of error. The level of significance is the measurement of the statistical significance. It defines whether the null hypothesis is assumed to be accepted or rejected. It is expected to identify if the result is statistically significant for the null hypothesis to be false or rejected. ( .01 or .05 level of significance).
