8. Look at the dot-plots of the following two datasets: Dataset-1 = \{1, 2, 2, 3, 3, 3, 4, 4, 5\};
Dataset-2 = \{0, 1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6\}. Choose the most correct answer:
(a) Dataset-2 has more spread than Dataset-1
(b) Both the datasets have the same unique center (mean, median and mode)
(c) Dataset-1 has less dispersion than Dataset-1
(d) All of the above ((a) - (c)) are correct
(e) None of the above is correct
9. Choose the most correct answer for any arbitrary dataset.
(a) Mean tends to be larger than the median if the dataset is positively skewed
(b) Median tends to be higher than the mean if the dataset is negatively skewed
(c) Mean, Median and Mode are almost same if the data shows a symmetric bell-shaped pattern
(d) All of the above are correct
(e) None of the above is correct
10. Consider a dataset with the following five number summary and draw a boxplot.
Min = 10, Q1 = 30, Q2 = 50, Q3 = 70, Max = 90. We can say that (choose the most correct
answer):
(a) The dataset seems to be symmetric and bell-shaped
(b) The histogram of the dataset seems to have a longer right tail
(c) The histogram of the dataset seems to have a longer left tail
(d) All of the above are correct
(e) None of the above is correct
