Statistics

 

Walt : display data on histogram, tally chart

  • Walt : interpret information from histograms and tally marks eg. medium, mode, range, mean

I was able to put the information from the class scores onto a histogram and tally chart


  • The range for the first name scores was from 4-20
  • The range for the last name scores was from  2-21
  • The range for the full name scores was from 9-31
  • The mode for the first name scores was 8 
  • The mode for the last name scores was 7 
  • The mode for the full name scores is 22
  • The medium for the first name scores is 10
  • The medium for the last name scores is 9.5
  • The medium for the full name scores is 21
  • The mean is when you add all of the number or data together, then you count how many numbers you have and then divide it by that number and that is your answer.
  • The median  is when you put the numbers in order from least to great then you find the middle number  and then that is  your answer, but if you have two numbers in the middle you add those together and then divide it by two then that is your answer.
  • The mode is the score that appears the most times.

I found this tricky  because we had to keep repeating again and again because we keep pushing the wrong number on the calculator  so i had a buddy to help me.
Next time i want to do this again because it was fun .
Here is the frog Video about mode mean and median
