a.
To draw: A histogram of given data using five intervals beginning with
a.
Explanation of Solution
Given Information: A table showing the IQ scores is given.
Histogram:
Drawing the axes and a bar to represent the frequency of each interval,
b.
To describe: Measures of center and variation representing the data best.
b.
Answer to Problem 10E
Median and five-number-summary respectively.
Explanation of Solution
Given Information: A table showing the IQ scores is given.
Because most of the data resides at left side and tail extends the right, distribution is skewed right. As the distribution is skewed, best measure for center is median and that for variation is five −number summary.
c.
To interpret: The shape of the distribution in part (a) as more and more IQ scores are included.
c.
Explanation of Solution
Given Information: A table showing the IQ scores is given.
The shape of the distribution will become symmetric after inclusion of more data because majority of human population have IQ lying in a particular range.
