You find the mean by adding the same numbers and dividing by the numbers involved. Eg if you have 45, 45 which are supposed to occupy the 4th and 5th position. 4+5=9÷2 =4.5 so you fill in 4.5 for each of the 45 positions then you start the next ranking with the 6th position.

N is how many different data sets there are so because there were 5 lots of different numbers it's 5 If it was something like 10 different sets of data n would be 10
Thank you for the clear and concise explanations
How do I know when to use this formula rather than the extended rs formula?
What if you have two variables that are the same figures?

@@charlesub1457not really, you'll add both of them and divide them by 2, then that'll be their figure

1 divided by 10 is 0.1. How did you get 0.9?
Because 1- 0.1 =0.9
@@ola_agh I didn’t add the 1 -
Thank you
Why is n 5?

question how did you got 0.9
😅
Because ,1-1\10=0.9@@ndaziharuna4820
