Progress Check: Mean, Mode, Median & 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 count of numbers.

Front

How do you calculate the mean of the numbers 2, 57, 38, 42, and 6?

Back

Add the numbers: 2 + 57 + 38 + 42 + 6 = 145. Then divide by the count of numbers (5): 145 / 5 = 29.

Front

What is the definition of range in a data set?

Back

The range is the difference between the largest and smallest numbers in a data set.

Front

How do you find the range of the numbers 2, 57, 38, 42, and 6?

Back

Identify the largest number (57) and the smallest number (2). Then subtract: 57 - 2 = 55.

Front

What is the median of a data set?

Back

The median is the middle value when the numbers are arranged in order from smallest to largest.

Front

How do you find the median of the numbers 2, 57, 38, 42, and 6?

Back

First, arrange the numbers in order: 2, 6, 38, 42, 57. The median is the middle number, which is 38.

Front

What is the importance of ordering numbers when finding the median?

Back

Ordering numbers is essential because the median is defined as the middle value, which can only be determined when the data is sorted.

Front

Can a data set have more than one median?

Back

No, a data set can only have one median, which is the middle value.

Front

What is the mode of a data set?

Back

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

Front

How do you determine the mode of the numbers 2, 57, 38, 42, and 6?

Back

In this set, there is no mode because all numbers appear only once.
