TEST Mean, Median, Mode and 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, first sort the data from least to greatest. If there is an odd number of values, the median is 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

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

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

True or False: The median can be found without sorting the data first.

Back

False. The data must be sorted from least to greatest to find the median.

Front

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

Back

The mode is 5, as it appears most frequently.

Front

What is the median of the following set: 1, 3, 3, 6, 7, 8, 9?
