Question

now it is your turn to practice finding measures of central tendency. try to answer the three questions below.
measures of central tendency
5, 8, 8, 10, 11, 11, 11, 12, 15, 16, 16, 16, 20, 20
how many modes does this data set have?
1
2
3
4
2 of 3
submit

Explanation:

Step1: Recall mode definition

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

Step2: Count frequencies

In the data - set 5, 8, 8, 10, 11, 11, 11, 12, 15, 16, 16, 16, 20, 20:

• The number 8 appears 2 times.
• The number 11 appears 3 times.
• The number 16 appears 3 times.
• The number 20 appears 2 times.
• The numbers 5, 10, 12, 15 appear 1 time each.

Step3: Determine number of modes

Since both 11 and 16 have the highest frequency (3 times) and other numbers have lower frequencies, there are 2 modes.
