Question

I need some help on the test. My grades an F and I’m trying to raise it. I’m not asking for the answers but I’m asking for a website or something that can help me through and get a good grade on this. Thank you! The first question is

What are the mean,median,mode, and range of the data set given the altitude of lakes in feet:
-12,-9,-14,-39,-49,-18,-43?

Answer 1

Mean = ∑x/n

Median = arranged in order of value, middle most score(s)

Mode = most frequent occurring score.

Range = highest score - lowest score

I'll let you do the calculations.
