Explain how to find the mean hat size of four students.

I don't understand this question, could I get some help?

Add the hat sizes of the four students (which for some reason are usually denoted by numbers between 6 and 8) and divide the sum by 4.

They want to know if you know how to tell them how to get the mean using mathematical language in your sentence answer. If you know how to calculate the mean then plug the words of hat and four students into that sentence. Attempt and i'll check your answer

Would it be: To find the mean you would meausure the size of 4 students heads, add the calculations together and divide that by 4?

Mr.L is that correct?

That sounds good to me but i would include the word average in a second sentence like " That is how i would find the average hat size." Teachers love to see math in pictures , words and numbers! I should know, i teach.

what is attempt
