What is the median?

Back

The median is the middle value in a set of numbers when they are arranged in order from least to greatest.

Front

If the data set is 3, 7, 7, 2, 5, what is the mode?

Back

The mode is 7, as it appears most frequently.

Front

Calculate the range of the following data set: 10, 15, 20, 5.

Back

The range is 20 - 5 = 15.

Front

What is the formula to calculate the mean?

Back

Mean = (Sum of all values) / (Number of values).

Front

If a set of numbers is 4, 8, 6, 5, what is the median?

Back

First, sort the numbers: 4, 5, 6, 8. The median is (5 + 6) / 2 = 5.5.

Front

In a data set of 5, 5, 5, 10, what is the mode?

Back
