Question

the data set shows the numbers of flowers that students on a field trip correctly identified. what is the mode of the data set? 2 0 5 7 8 9 8 2 1 8 8 only 2 only 2 and 8 no mode

Explanation:

Step1: Recall mode definition

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

Step2: Count number frequencies

In the data - set 2, 0, 5, 7, 8, 9, 8, 2, 1, 8:

• The number 2 appears 2 times.
• The number 0 appears 1 time.
• The number 5 appears 1 time.
• The number 7 appears 1 time.
• The number 8 appears 3 times.
• The number 9 appears 1 time.
• The number 1 appears 1 time.

Step3: Determine the mode

Since 8 appears 3 times and 2 appears 2 times, and 8 appears more frequently than any other non - 8 number, and 2 also has a relatively high frequency compared to the other single - occurrence numbers, the mode is 2 and 8 (bimodal data - set).

Answer:

C. 2 and 8
