Mean, Median, Mode

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 calculate the mean of the numbers: 2, 57, 38, 42, 6?

Back

Mean = (2 + 57 + 38 + 42 + 6) / 5 = 29.

Front

What is the median of a set of numbers?

Back

The median is the middle value in a list of numbers sorted in ascending order. 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 the numbers: 4, 2, 7, 4, 3?

Back

Sorted: 2, 3, 4, 4, 7. Median = 4.

Front

What is the mode of a set of numbers?

Back

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

Front

What is the mean of the numbers: 90, 100, 95, 85, 60, 80?

Back

Mean = (90 + 100 + 95 + 85 + 60 + 80) / 6 = 85.

Front

How do you find the median of the numbers: 36, 42, 28, 52, 48, 36, 31?

Back

Sorted: 28, 31, 36, 36, 42, 48, 52. Median = 36.

Front

What is the formula for calculating the mean?

Back

Mean = (Sum of all values) / (Number of values).

Front

If a set of numbers has no repeating values, what can you say about the mode?

Back

If there are no repeating values, the set has no mode.

Front

What happens to the mean if you add a new number that is higher than the current mean?

Back

The mean will increase.
