Mean, Median and Mode flashcardziz

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 3, 4, 5, and 6?

Back

Add the numbers: 3 + 4 + 5 + 6 = 18. Then divide by the count of numbers (4): 18 / 4 = 4.5.

Front

What is the median of a set of numbers?

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

How do you find the median of the numbers 10, 20, 30, 40, 50?

Back

Arrange the numbers in order (already arranged). The median is 30, the middle value.

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 mode of the numbers 1, 2, 2, 3, 4?

Back

The mode is 2, as it appears most frequently.

Front

What is the range of a set of numbers?

Back

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

Front

How do you calculate the range of the numbers 5, 10, 15, 20?

Back

Range = highest value - lowest value = 20 - 5 = 15.

Front

What is the formula for calculating the mean?

Back

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

Front

If the numbers are 4, 8, 6, 5, what is the mean?

Back

Mean = (4 + 8 + 6 + 5) / 4 = 5.75.
