Mean, Mode, Median

Front

What is the mean in statistics?

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 a set of numbers?

Back

To calculate the mean, add all the numbers together and then divide by the total number of values in the set.

Front

What is the median in a data set?

Back

The median is the middle value when a data set is ordered from least to greatest. If there is an even number of values, the median is the average of the two middle numbers.

Front

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

Back

To find the median, first arrange the numbers in ascending order, then identify the middle number (or average the two middle numbers if the count is even).

Front

What is the mode in statistics?

Back

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

Front

How do you determine the mode of a set of numbers?

Back

To determine the mode, count how many times each number appears in the set; the number with the highest frequency is the mode.

Front

What is the difference between mean, median, and mode?

Back

Mean is the average, median is the middle value, and mode is the most frequently occurring value in a data set.

Front

What is an example of calculating the mean?

Back

For the numbers 5, 10, and 15, the mean is (5 + 10 + 15) / 3 = 10.

Front

What is an example of finding the median?

Back

For the numbers 3, 1, 4, 2, the median is 2.5, as the ordered set is 1, 2, 3, 4.

Front

What is an example of identifying the mode?

Back

In the set {1, 2, 2, 3, 4}, the mode is 2, as it appears most frequently.
