The average mean is: (11+12+13+14+15)/5 = 13

Mean = Average (14 + 6 + 4 + 12)/4 = ? (36)/4 = 9 Mean of the data is 9.

In order to find the weighted mean of this set of the data, we need to know the weight for each data in the set, and this information is not given in your question.Definition: When each number ai is to have weight wi, the weighted mean is equal to(w1a1+w2a2 + ... + wnan)/(w1 + w2 + ... + wn).

6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16

Mean = 14 Median = 12 Mode = 12

Mean = Average (14 + 6 + 4 + 12)/4 = ? (36)/4 = 9 Mean of the data is 9.

12 + 23 + 14 + 11 = 60/4 = 15 The average is therefore 15.

the mean of the dataset 6, 7, 12, 14, 16, 17 is 12. to get the mean (or average) of a dataset, you add the numbers of the dataset together and then divide by the number of data (in this case there are 6 pieces of data) (6+7+12+14+16+17)/6 = 12

6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16

Mean = 14 Median = 12 Mode = 12

what is the mode of the following data 18, 17, 12, 14, 8, 21, 10, 11, 19, 20, 10, 5, 17, 12, 10, 20

11

7, 10, 11, 12, 13, 14, 17

Sum = 4+8+8+11+12+14+16 = 73 Number = 7 So mean = 73/7 = 10 3/7 or 10.4258714...

Let write the data in an increasing order: p q r s t.Since the median is 14, then r = 14, and we have: p q 14 s t.Since the mode is 11, then p = q = 11.Since the range is 9, then t - p = 9, t - 11 = 9, and t = 20.So, we have: 11 11 14 s 20.Since the mean is 25, we have:(11 + 11 + 14 + s + 20)/5 = 25(56 + s)/5 = 25 multiply by 5 to both sides56 + s = 125 subtract 56 to both sidess = 69So the data set is: 11 11 14 69 20
