Mean, Median, Mode, Range

Front

What is the definition of Mean?

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 Median?

Back

To find the median, arrange the numbers in ascending order and identify the middle number. If there is an even number of observations, the median is the average of the two middle numbers.

Front

What is the definition of Mode?

Back

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

Front

How do you determine 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 formula for calculating Mean?

Back

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

Front

What is the significance of the Median in a data set?

Back

The median provides a measure of central tendency that is less affected by outliers than the mean.

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.

Front

What is the relationship between Mean, Median, and Mode in a normal distribution?

Back

In a normal distribution, the mean, median, and mode are all equal.

Front

How do you find the Median in a data set with an odd number of values?

Back

For an odd number of values, the median is the middle value after sorting the data.

Front

How do you find the Median in a data set with an even number of values?

Back

For an even number of values, the median is the average of the two middle values after sorting the data.
