Question

The range of 0,15,-11,-17,18,35,25,35,29 for the given data, find the A)range B)mean C)median D)mode

Answer 1

formula for range is highest observation minus lowest observation therefore 29 - 0 equals 29.  for mean you can use Sigma... I cannot solve it by Sigma sign so the first step can't be done therefore I will start by the second step the answer will be same then too.. The sum is 129 for all the data you have given the number of data you have given 9..129 upon 9 gives out the answer as 14 . 9 bar. Number of observation here is 9 that is all because it can be divided by 2 therefore the median is n + 1 upon 2 therefore 9 + 1 upon 2 .. 10 by 2 is 5... Mode is the highest repeating data or we can say the popular value therefore 35 is mode here   I hope it helps you just read out the thing and you will get it very well
