Certain kinds of tumors tend to recur. The following data represent the lengths of time, in months, for a tumor to recur after chemotherapy (Reference: D.P. Byar, Journal of Urology, Vol. 10, pp. 556-561).
22 54 46 25 49 50 1 59 39 43 39 5 9 38 18 14 45 54 59 46 50 29 12 19 36 38 40 43 41 10 50 41 25 19 39
(a) Make a dotplot for the data above regarding the recurrence of tumors after chemotherapy.
(b) Compare the dotplot to a histogram of the data. (Select all that apply.)
-The raw data can be retrieved from the dotplot, but not the histogram.
-Both show the concentration of most of the data in two peaks, one from 13 to 24 and another from 37 to 48.
-The raw data can be retrieved from the histogram, but not the dotplot.
-Histograms show the frequency of individual data values.
-Dotplots show the frequency of individual data values.
Solution: (a) Make a dotplot for the data above regarding the recurrence of tumors after chemotherapy.
Answer: The dotplot is given below:
(b) Compare the dotplot to a histogram of the data. (Select all that apply.)
Answer: The correct options are:
The raw data can be retrieved from the dotplot, but not the histogram.
Both show the concentration of most of the data in two peaks, one from 13 to 24 and another from 37 to 48.
