Question

a) Find the Mean Score for the Statistics Quiz (X), and the Mean for the Math Quiz (Y) b) Use the pooled (weighted) mean formula to find the pooled (weighted) mean for the Math Quiz scores given above, and another section of 6 students who had a mean score or 10

 

x= 3,7,5

y=10,22,16

Expert Solution
Step 1

Given :  Score for the Statistics Quiz (X), and the score for the Math Quiz (Y) is provided . 

 

  • The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:

Mean=Sum of termsNumber of terms

 

Statistics Quiz (X) : 

Sum of terms = 3 + 7 + 5 = 15 

Number of terms = 3 

Mean=Sum of termsNumber of terms

          = 153

Mean = 5

Math Quiz (Y) :  

Sum of terms = 10 + 22 +16 = 48

Number of terms = 3 

Mean=Sum of termsNumber of terms

          = 483

Mean = 16
