Answer 1

I believe you had this exact same problem posted a few minutes back, and that I gave you some pointers. Are you re-posting this problem? If so, why?

Answer 2

i dont get it

Answer 3

Why repost the question then?
I suggested that you actually calculate the mean, the mode and the median. Have you done so?

Answer 4

no

Answer 5

Sorry this question is difficult for you. Still, I'd hope you'd put some of your own time and effort into solving it, especially when someone makes pertinent suggestions.
Do you know how to find the mean, the mode and the median? These operations are basic to statistics and must be known and understood.

Answer 6

Without calculating the mean, the mode and the median, you have very little that you can compare and interpret.

Answer 7

im not shere what that is

Answer 8

What kind of references have you? Do you have a textbook? Does your course have online study materials? Have you done internet searches for "mean," "mode," "median?"

Answer 9

umm no i dont think so

Answer 10

the mean is used more often (a lot more often) to describe how a class of students did on an exam. I'm sure you've heard "class average" before...that's the mean.

What kind of references have you? Do you have a textbook? Does your course have online study materials? I'm glad to help, but I do expect that you'll have made some effort to learn this material on your own before asking for help.

Answer 11

Please do yourself a favor and look up "mean" / "average". This is one of the most basic concepts of statistics.

Answer 17

The mean or average of a set of data is found by adding up all the data points and then dividing by the number of data points. What is the mean of your data set?

the mode is the data value that shows up most often. What is the mode of your data set?

If you arrange your data so that it's in increasing order from left to right, and the number of data points is ODD, then your median is the data point that's in the middle of your data point arrangement.
