7, 9, 10, 13, 11, 7, 9, 19, 12, 11, 9, 7, 9, 10, 11.

• 7

• 9

• 10

• 11

The following numbers represent the ages of people on a bus:

3, 6, 27, 13, 6, 8, 12, 20, 5, 10.

Calculate their mean of their ages.

• 11

• 6

• 9

• 110

These numbers are taken from the number of people that attended a particular church every Friday for 7 weeks:

62, 18, 39, 13, 16, 37, 25.

Find the mean.

• 25

• 210

• 62

• 30

Which of the following is a measure of central tendency?

• Mean

• Standard Deviation

• Range

• Variance

What is the mode?

• The value between the minimum and maximum values of a variable

• The average score or value

• The middle value among some scores of a variable

• The most frequent response or value for a variable

What is the main problem associated with the mean value of some data?

• It is affected by the mode

• It is difficult to compute

• It is not a representative measure

• It is sensitive to outliers

What is the median?

• The middle value among some scores of a variable

• The average score or value

• The most frequent response or value for a variable

• The value between the minimum and maximum values of a variable

Which of the following has this formula?

• Weighted Mean

• Mean

  (Grouped data)

• Mean

  (Ungrouped data)

• Median

  (grouped data)
