The mean You have to first put the numbers in order 18,22,26,34,39,42 To find the median you have to find the number that’s in the middle and since there are two of them, you have to find the average of them 26+34=60 60/2=30 Median is 30 To find the mean, you have to add everything together and then divide it by 6. 18+22+26+34+39+42=181 181/6= 30.17
Now you have to add the 65 18,22,26,34,39,42,65 The middle number is 34 Median=34 18+22+26+34+39+42+65=246 246/7=35.14 Now you just have to subtract new median-old median 34-30=4 New mean-old mean 35.14-30.17=4.97 So the mean will increase more
