How is the mean of a data set calculated?

The mean is calculated by adding all values in the data set and dividing by the total number of values.

What is the median of the data set: 3, 7, 9, 2, 5?

First arrange in order: 2, 3, 5, 7, 9. The median is 5, the middle value.

When a data set has an even number of values, how is the median determined?

The median is the average (mean) of the two middle values after arranging the data in ascending order.

What is the mode of a data set, and what does it mean if a set is bimodal?

The mode is the value that appears most frequently. A bimodal data set has exactly two values that each appear with the highest frequency.

How is the range of a data set calculated?

The range is calculated by subtracting the smallest value from the largest value in the data set.
