Answer:
Step-by-step explanation:
a, First arrange the data in ascending order:
77 79 80 81 84 84 86 88 92 95 <-- ten numbers.
Mean = sum of the numbers / 10
= 846/10
= 84.6.
The median is the middle number in the ordered list, or if there are an even number of values, the mean of the 2 middle numbers. There are 10 numbers here, so the median = (84+84)/2 = 84
Median = 84.
The mode is the value that occurs most. Here we have 2 84's so
Mode = 84.
Parts b to d are done in the same way as for the above, note if there is no mode write None.
For the stem leaf data first write out individual vales and then proceed as in a).
Values = 31 32 40 41 43 44 45 46 47 51 54 52 60 66
