Mean, Mode & Median

HINT

The mean is the sum of the value divided by the number of values.

1 / 5

What is the mean of the numbers \(1,2,2,3\)?

HINT

If there is an even number of values, the median will be the average of the two middle numbers.

2 / 5

What is the median of the numbers \(1,2,2,3\)?

HINT

The mode is the most common value in the set.

3 / 5

What is the mode of the numbers \(1,2,2,3\)?

HINT

An outlier is a value that is much larger/smaller than the other values.

4 / 5

The set \(1,2,2,3\) contains outliers.

HINT

The additional value is the same as the original mean.

5 / 5

The set \(1,2,2,3\) has the same mean as the set \(1,2,2,2,3\).
