Key Statistics Explained

Mean

Mean is the average of all values. It is calculated by dividing the sum of values by the number of values.

Median

Median is the middle value after sorting the data. If there are two middle values, their average is used.

Mode

Mode is the value that appears most often in the data set.

Range

Range is the difference between the maximum and minimum values.

Variance and Standard Deviation

Variance and standard deviation measure how spread out the values are. A higher standard deviation means the data values are more spread out from the mean.

Quartiles and IQR

Quartiles divide data into four parts. Q1 is the lower quartile, Q3 is the upper quartile, and IQR is the difference between Q3 and Q1.
