mean



  • add all the numbers together and divide by the amount of numbers you added










median



  • middle value








mode



  • is the most common # in the data











range



  • the least and the most # and subtract it and you'll get the range

hi elmane! good job! haha, but you forgot to attach links to the mmmr, you didnt explain what you're suppose to do if theres two middle numbers when finding the median, you didnt mention the two important stuff about the mode, and in your range picture, it says 1-4=3, but its suppose to be 4-1=3. :) i just wanted to let you know. :)
