[MulderMan]

hi, could someone that has done gcse mathematics coursework or similar tell me or point me in the right direction of the advantages and disadvantages of using the mean and median?

 

thanks

Advantage of Mean: takes all values used into account.

Disadvantage: Answer oftendistorted if there are some very small of some very large extremes to the data.

 

Advantages of Median: Ignors the extremeties so the value is not effect by the difference in the values. this is particularly improtant when then distribution of the data is heavily skewed.

Disadvatages of median: It does not take into account all of the items of data and so is not a true representation of the entirity.

 

Hope this helps!
