Intro to Mean, Median, Mode, Range

Front

What is the formula to calculate the MEAN of a set of numbers?

Back

To find the MEAN, add all the data points together and then divide by the number of data points.

Front

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

Back

The MEDIAN is the middle number when the numbers are arranged in order.

Front

What is the MEDIAN of the following set of numbers: 4, 2, 9, 2, 3?

Back

The MEDIAN is 3.

Front

What is the MEDIAN of the following set of numbers: 8, 0, 4, 0, 3, 2, 8?

Back

The MEDIAN is 3.

Front

What is the definition of MODE in a data set?

Back

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

Front

What is the MODE of the following set of numbers: 5, 4, 4, 8, 2?

Back

The MODE is 4.

Front

How do you calculate the RANGE of a set of numbers?

Back

The RANGE is calculated by subtracting the least number from the greatest number in the set.

Front

What is the RANGE of the following set of numbers: 8, 4, 12, 1, 9, 4, 2?

Back

The RANGE is 11.

Front

What is the relationship between MEAN, MEDIAN, and MODE in a symmetric distribution?

Back

In a symmetric distribution, the MEAN, MEDIAN, and MODE are all equal.

Front

What is the relationship between MEAN, MEDIAN, and MODE in a skewed distribution?

Back

In a skewed distribution, the MEAN is pulled in the direction of the skew, while the MEDIAN is less affected, and the MODE remains the most frequent value.
