Question
(b)A boxplot gives you a visual representation of the average value using the median, and also tells you how the data are spread out based on the size of the box and the lengths of the whiskers. How do the average travel times compare for public and private transport? Use your boxplots from part (a) to explain your answer. (ü) Are the data more spread out for using public transport or using private transport? Use your boxplots from part (a) to explain your answe (c) Use the boxplot for private transport to say whether the data are symmetrical or skewed. If the data are skewed, then state whether they are skewed to the left or skewed to the right, explaining your reasoning briefly (d) Create histograms for each of the datasets, using a start value of 20 and an interval of 2. Include either a printout of your histograms or a sketch drawn by hand with your answer to this question. If you draw 13] histograms by hand, then y0? should use squared paper and the same aris scale for both histograms to make it easy to compare them. (e) Comment on one aspect of the time spent travelling to work that can be seen more easily on the histograms than on the boxplots.Explanation / Answer
I hope your 'new data 7' is data for private transport and 'new data 8' is for public transport.
b.
i. from the boxplots, it is clear that average time spent in public transport is more than the same in private transport, as the central line inside the box of public transport is away in the right side from the same in private transport.
ii. From the boxplots, it is clear that the 'new data 7' is more spreaded than 'new data 8', as the box takes more area in case of 'new data 7'.
c. From te boxplot of 'new data 7' we observe:
the central line inside the box doesnot divide the box in two equal parts. So, the data is skewd
from the box plot of 'new data 8' we observe:
the central line divides the box in two perfectly equal parts. Again the length of the whiskers are also same. So, we can conclude that the data of 'new data 8' is symmetrical.
e.
