Study Notes

Statistical Concepts

Mean: The average of a set of numbers. It is calculated by summing all the values and dividing by the total number of values.
Frequency: The number of times a particular value occurs in a set of data.
Quartiles: Values that divide a dataset into four equal parts. There are three quartiles: Q1 (the first quartile), Q2 (the second quartile, also known as the median), and Q3 (the third quartile).
Correlation: A statistical measure that describes the strength and direction of the relationship between two variables. Correlation can be positive (as one variable increases, the other increases), negative (as one variable increases, the other decreases), or zero (no relationship).
