Mean, Median, Mode, and Range

Front

What is the mode of a set of numbers?

Back

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

Front

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

Back

To find the mean, add up all the numbers in the set and divide by the total number of items.

Front

What is the median in a data set?

Back

The median is the middle value when the numbers are arranged 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 range of a set of numbers?

Back

The range is calculated by subtracting the smallest number in the set from the largest number.

Front

What is the mode of the following numbers: 4, 4, 6, 6, 2, 2, 6, 2, 4, 2?

Back

The mode is 2, as it appears most frequently.

Front

If a data set has no repeating numbers, what is the mode?

Back

If there are no repeating numbers, the data set has no mode.

Front

What is the importance of the mean in statistics?

Back

The mean provides a measure of central tendency, giving an average value that represents the data set.

Front

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

Back

First, arrange the numbers in ascending order: 28, 31, 36, 36, 42, 48, 52. The median is 36, the middle value.

Front

What does it mean if the mode is the same as the median?

Back

If the mode is the same as the median, it indicates that the most frequently occurring value is also the middle value of the data set.

Front

Can a data set have more than one mode?

Back

Yes, a data set can be bimodal (two modes) or multimodal (more than two modes) if multiple values appear with the same highest frequency.
