Mean, Mode, Median, Outliers and Normal Distribution

The mean is:

• The middle value

• The sum of the values divided by number of values

• The most frequent value

• The middle value when in ascending order

The median is:

• The middle value

• The sum of the values divided by the number of values

• The most frequent value

• The middle value when arranged in ascending order

What is the mode?

• The value that occurs the most

• The average

• The largest value subtract the smallest value

• The middle value

Find the mean of the numbers below:

5, 11, 2, 12, 4, 2

• 4.1

• 6

• 4.5

• 4

What is the range?

• The average

• The largest value subtract the smallest value

• The middle value when arranged in ascending order

• The value that occurs the most

An outlier is:

• A value that is distinctly separate from the rest of the data

• The highest value in a data set

• The lowest value in a data set

• The value that is the least frequent

A set of data can have more than one mode.

• True

• False

A set of data can have more than one median.

• True

• False

If there is an even number of values in a set of data how do you find the median?

• Order the values in ascending order and find the middle value

• Order the values in ascending order then add the 2 middle values and divide by 2

• You can have more than one median

Identify the outlier for the given data:

23, 34, 27, 7, 30, 26, 28, 31, 34

• 7

• 23

• 31

• 34
