Answer:
As, you will observe the line plot, the number of times 12 adults went to supermarket
Adult Supermarket
1 1
2 2
3 4
1 6
1 7
1 10
2 15
1 20
As, you will see , in the line plot most of data values are on the left of median, so graph of data set is skewed left.
But when 5 more adults are included in the data,mode has decreased and median has increased, as median being 10, the data values have gone to right it means these adults have traveled more than 10 to supermarket due to which median increases and mode decreases.
Also, it is not necessary that , where i have marked cross is only true, you can mark cross on any number between 10 to 20 as well as both number included that is [10,20].
So, graph of data set is Rightly Skewed (Positive Skewness)
