Question

Example 7.19 examined rainfall data for Minneapolis- St. Paul. The square-root transformation was used to obtain a distribution of values that was more symmetric than the distribution of the original data. Another transformation that has been suggested by meteorologists is the cube root: transformed value = (original value)1/3. The original values and their cube roots (the transformed values) are given in the following table:
Construct a histogram of the transformed data. Compare your histogram to those given in Figure 7.33. Which of the cube-root and the square-root transformations appears to result in the more symmetric histogram?
