Unit 11 Assessment - Mean, Median, Mode, and Range

Front

What is the mean?

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

What is the median?

Back

The median is the middle value in a set of numbers when they are arranged in order. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is the mode?

Back

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

Front

What is the range?

Back

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

Front

What does 'fair share' mean in terms of distribution?

Back

'Fair share' refers to distributing items equally among a group, ensuring that each person receives the same amount.

Front

How do you find the mean of the numbers 4, 8, 6, and 10?

Back

Add the numbers: 4 + 8 + 6 + 10 = 28. Then divide by the count of numbers: 28 ÷ 4 = 7. So, the mean is 7.

Front

How do you find the median of the numbers 3, 1, 4, 2?

Back

First, arrange the numbers in order: 1, 2, 3, 4. Since there are 4 numbers (even), the median is the average of the two middle numbers: (2 + 3) ÷ 2 = 2.5.

Front

What is an example of finding the mode in the set: 1, 2, 2, 3, 4?

Back

The mode is 2 because it appears most frequently in the set.

Front

If the highest number is 10 and the lowest is 2, what is the range?

Back

The range is 10 - 2 = 8.

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a way to display data where each number is split into a 'stem' (the leading digit) and a 'leaf' (the trailing digit).
