The median is the middle value of a dataset when the numbers are arranged in ascending or descending order. It divides the dataset into two equal halves.
How to find the median:
Sort the data from smallest to largest.
If the number of values is odd, the median is the middle number.
If the number of values is even, the median is the average of the two middle numbers.
Example 1 (Odd number of values):
Data: 3, 7, 9, 12, 15
Median = 9 (middle number)
Example 2 (Even number of values):
Data: 2, 5, 8, 10, 12, 15
Middle numbers = 8 and 10
Median = (8 + 10) / 2 = 9

A Repeated Measures ANOVA is a statistical test used to analyze data where the same subjects are measured multiple times under different conditions or at different time points. It is used to determine whether there are significant differences in the means of the measurements across these conditions or times.

A t-test is a statistical test used to determine whether there is a significant difference between the means of two groups. It's especially useful when working with small sample sizes and is commonly used in fields like psychology, medicine, and social sciences. The t-test assumes the data is normally distributed and helps answer questions like whether two groups differ significantly on a particular variable or whether a single group's mean differs from a known or hypothesized value.
There are three main types of t-tests:
1. One-sample t-test
Compares the mean of a single sample to a known or hypothesized population mean.
2. Independent (Two-sample) t-test
Compares the means of two independent groups to see if they are significantly different from each other.
3. Paired (Dependent) t-test
Compares means from the same group at different times (such as before and after a treatment) or under different conditions.

Regression analysis is a statistical method used to examine the relationship between two or more variables. It allows us to see how changes in one variable (often called the "independent variable" or "predictor") are associated with changes in another variable (called the "dependent variable" or "outcome"). Regression analysis is widely used in various fields, including economics, biology, engineering, and social sciences, to make predictions, evaluate trends, and understand causal relationships.

ANOVA, or Analysis of Variance, is a statistical method used to determine if there are significant differences between the means of three or more groups. It assesses whether observed variations in data are due to true differences between groups or just random chance. By comparing the variance within groups to the variance between groups, ANOVA helps identify whether one or more groups differ significantly from the others.

Descriptive statistics is a branch of statistics that involves summarizing and organizing data so that it can be easily understood. Rather than drawing conclusions or making inferences about a population, descriptive statistics focuses on presenting the data in a way that highlights important features and patterns.
