Question

Given the altitude of lakes in feet: –12, –9, –14, –39, –49, –49, –18, –43, find the mean, median, mode, and range

Answer 1

-9 -12 -14 -18 -39 -43 -49 -49

Mean: Add the numbers and divide by 8

Median: The middle number. Since there's an even number, take the average of the middle two numbers

Mode: The number that appears the most

Range: 49 - 9 = ?

Answer 2

**ANSWER: A mean = –28.5, median = –29.1, mode = –49, range = 40

First put them in order:
- 49, - 49 , - 43 , -39 , -18, -14, -12, -9
Add the two middle numbers -39 and -18, it equals -57
Divide - 57 and 2, it equals - 28.5 <--- MEAN

Second add all the numbers together, it equals - 233, then divide by 8, which equals
- 29.1 <---MEDIAN

MODE is the number that happens most, which is -49 <--- MODE

The range is -49 - ( -9 ) = - 40 <-----RANGE

Answer 3

The answer is...
D - or...
mean= 29.1, median= 28.5, mode= -49, range= 40

Mrs. sue is correct about how to find these numbers.
