Question

Here is to my last q

Answer 1

Answer: D (Mean is 85)

Step-by-step explanation:

"The list below shows the quiz scores for a group of students.

95, 80, 80, 85, 80, 85, 90"

The choices talk about median and mode so we find those first:

Median: find by taking which is the middle number when the data is from low to highest

1) rearrange them from low to high

80, 80, 80, 85, 85, 90, 95

2) find middle number

80, 80, 80, 85, 85, 90, 95

The median is 85

Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers

1) add 80, 80, 80, 85, 85, 90, 95 and get 595

2) There are 7 total numbers so do 595/7 = 85

The mean is 85

D is the correct answer

why?

A is wrong because they are 85 not 80

B is wrong because it is 85 not 80

C is wrong because it is 85 not 80

D is right because it is 85!

Answer 2

Mode: value that occurs most
Mean: average (add all values then divide by the amount of number)
Median: middle number

Mode: 80 (appears the most)
Mean: 95 + 80 + 80 + 85 + 80 + 85 + 90 = 595/7 = 85, the mean is 85
Median first put them in order
80, 80, 80, 85, 85, 90, 95
The median is the middle which is 85

Which statement matches?

Solution: D
