Mean, Median, Mode, & Range

Front

What is the mean of a set of numbers?

Back

The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the total count of numbers.

Front

How do you find the median of a data set?

Back

To find the median, arrange the numbers in ascending order and identify the middle number. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is the mode of a data set?

Back

The mode is the number that appears most frequently in a data set. A data set can have one mode, more than one mode, or no mode at all.

Front

What is the range of a set of numbers?

Back

The range is the difference between the highest and lowest values in a data set.

Front

Can a data set have more than one mode?

Back

Yes, a data set can have multiple modes if two or more numbers appear with the same highest frequency.

Front

Find the mean of the following numbers: 80, 90, 100.

Back

Mean = (80 + 90 + 100) / 3 = 90.

Front

Find the median of these numbers: 1, 3, 3, 6, 7, 8, 9.

Back

Median = 6 (the middle number in the ordered list).

Front

What does it mean if a data set has no mode?

Back

It means that no number appears more than once in the data set.

Front

If the mode of a test score is 94, what can we conclude?

Back

More students received a score of 94 than any other score.

Front

Calculate the range of the following numbers: 4, 8, 15, 16, 23, 42.

Back

Range = 42 - 4 = 38.
