descriptive statistics

Mean

The mean, or average, is calculated by adding all values and dividing by the count. It's sensitive to outliers.

Median

The median is the middle value in a data set when arranged in order. It divides the data into two equal halves.

Mode

The mode is the value that appears most frequently in a data set. There can be more than one mode if multiple values tie.

Range

The range measures the spread of data by subtracting the smallest value from the largest. It's simple but sensitive to outliers.

Standard Deviation

Standard deviation quantifies data variation, showing how spread out values are from the mean.
