Answer:
i) Median=2
ii) Modal number of computers=1
iii) The mean is affected by outliers.
Step-by-step explanation:
i) The number of computers in a classroom is 3,15,1,2,1,30,2,1
We want to find the median of this data set.
We rearrange in ascending order to get:
1,1,1,2,2,3,15,30
The median is the average of the two middle numbers.
[tex] = \frac{2 + 2}{2} = 2[/tex]
ii) The modal number of computers is the number of computers with the highest frequency.
The most occurring number among the data set is 1.
Therefore the modal number of computers is 1.
iii) From the given date set, there is an outlier, which is 30.
Since, the meat is largely affected by outliers, it would not be a sensible average for this data.
