MEASURES OF CENTRAL TENDENCY (MODE)

Which of the following best describes the mean of a dataset?

• The most frequent value

• The middle value when the data is ordered

• The average value

• The difference between the highest and lowest values

Using the same dataset (2, 4, 4, 6, 8, 10), what is the median?

• 4

• 5

• 6

• 7

Using the same dataset (2, 4, 4, 6, 8, 10), what is the median?

• 2

• 4

• 6

• 8

Which of these statements is TRUE?

• The mean is always greater than the median.

• The mode is always the smallest value in the dataset.

• The median is not affected by extreme values.

• The mean can only be calculated for whole numbers.

The mode of a dataset is:

• Always unique

• The average of all values

• The most frequent value

• The middle value

Which measure of central tendency can be used for both numerical and categorical data?

• Mean

• Median

• Mode

• All of the Choices

Which of the following datasets has no mode?

• {1, 2, 2, 3, 4}

• {1, 2, 3, 4, 5}

• {1, 1, 2, 2, 3}

• {1, 1, 1, 2, 2, 2, 3}

A dataset can have:

• Only one mode

• More than one mode

• No mode

• All of the choices

If a dataset has two modes, it is called:

• Unimodal

• Bimodal

• Trimodal

• Polymodal

If all values in a dataset appear only once, the dataset:

• Has no mode

• Has a mode equal to the mean

• Has multiple modes

• Has a mode equal to the median
