Question

I dont understand mean or median. Can someone help?

Answer 1

Answer:

both of these are ways to kinda categorize numbers.

MEAN- you're finding the average. average and mean are synonymous. meaning they're the exact same. with the mean, all you have to do is add all the numbers up and then divide that by however many numbers you added up

lets say you need to find the mean of a domain and you're given this set of numbers:

{1,2,3,4,5,6,7}

the sum is 28. You divide it by 7 (bc thats how many numbers you added up) and you get your mean to be 4

The MEDIAN is going to be simpler than you may think. put all the numbers in numerical order, greatest to least or least to greatest. it doesn't matter.

Then find the number in the middle. Some people like crossing off the numbers on either end until you get to the center. So like marking off 1 then 7 then 2 then 6 etc.

The median is 4.

Step-by-step explanation:

Answer 2

Of course, I'm glad to help.

Mean is average. So for example, if I had the numbers 2,3,4, and 5 the mean would be 10.25.

The steps to getting mean are adding up all your numbers then dividing by the number of equalities you have.

Median is the middle number in your group. For example, if I had numbers 2, 3, 4, 5, and 6. The median would be 4 because that the number in the middle.

But when you have an even amount of numbers (for example 2,3,4,5) you'd add up the ones in the middle (3 and 4) then divide them by 2 (3+4=7/2). In this case, the median would be 3.5.

I know how hard school has been this year so it's understandable if you need help. You can always reach out to me in messages for more help.
