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.

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

@@Love_yourself_dear in a situation where there are more than 2 same variable, dividing by two would be wrong, you have to divide by the number of variables appeared

😅

Because 1- 0.1 =0.9

@@ola_agh I didn’t add the 1 -

Thank you

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

Add all of the x values (average temperature) and divide by total amount Add all of the y values (ice cream sales) and divide by total amount

I have paper 2 tmr , what did you end up getting for statistics?

@@christopherdula1213 Ended up with an mid tier grade 8 (so not close to a 7, but not necessarily close to a 9). Just remember with a course like stats, where there is very little content, if something came up in Paper 1, it will most certainly not re appear on Paper 2. Good Luck!

@@JaiPHANGURHA that's a good grade, thanks! 👍
