How do you find the median of a set of numbers?

Back

The mode is the number that appears most frequently in a data set.

Front

What is the range of a set of numbers?

Back

The range is the difference between the greatest and least numbers in a set.

Front

Find the mean of these numbers: 2, 4, 6, 8.

Back

The mean is (2 + 4 + 6 + 8) / 4 = 5.

Front

Find the median of these numbers: 1, 3, 3, 6, 7, 8.

Back

The median is 3, as it is the middle number in the ordered set.

Front

What is the mode of this data set: 5, 5, 6, 7, 8?

Back

The mode is 5, as it appears most frequently.

Front

Calculate the range of these numbers: 10, 15, 20, 25.

Back

The range is 25 - 10 = 15.

Front

If a data set has no repeating numbers, what is the mode?

Back

If there are no repeating numbers, the data set has no mode.

Front

What is the median of these numbers: 2, 3, 5, 7, 9, 11?

Back

The median is (5 + 7) / 2 = 6.
