Question

Marcus recorded the high temperature each day for a week. the daily high temperatures in degrees Fahrenheit were: 68,74,66,78,72,80, and 74 which best describes what 74 represents in this data set?
A. median only
B. mean and mode
C. median and mode
D. mode only

Answer 1

Answer:

The answer is C. median and mode.

Step-by-step explanation:

First, we have to ensure that the list of the set of data is from least to greatest: 66, 68, 72, 74, 74, 78, 80 .

The mean = (66 + 68 + 72 + 74 + 74 + 78 + 80) ÷ 7 = 512 ÷ 7 = 73.14 . (Note that the mean is not equal to 74.)

The median = middle number when the set of data is listed in order from least to greatest = the fourth number = 74.

The mode = the temperature that occurred the most = 74 .

These results prove that the median and mode best describe what 74 represents in the data set, because they are the same value.

Answer 2

74 represents the middle of the numbers listened. if you write them in numerical order then 74 would be in the middle of the numbers.
