Problem 1.66

Are there outliers in the smolt data? Refer to Exercise 1.64. (a) Find the IQR for the smolt data. (b) Use the 1.5 3 IQR rule to identify any outliers. (c) Make a boxplot for the smolt data and describe the distribution using only the information in the boxplot. (d) Make a modified boxplot for these data and describe the distribution using only the information in the boxplot. (e) Make a stemplot for these data. (f) Compare the boxplot, the modified boxplot, and the stemplot. Evaluate the advantages and disadvantages of each graphical summary for describing the distribution of the smolt reflectance data.

Step-by-Step Solution:

Problem 1.66

Are there outliers in the smolt data? Refer to Exercise 1.64.

(a) Find the IQR for the smolt data.

(b) Use the 1.5 3 IQR rule to identify any outliers.

(d) Make a modified boxplot for these data and describe the distribution using only the information in the boxplot.

(e) Make a stemplot for these data.

(f) Compare the boxplot, the modified boxplot, and the stemplot. Evaluate the advantages and disadvantages of each graphical summary for describing the distribution of the smolt reflectance data

Step by step solution:

Step 1:

Exercise 1.64 data:

The interquartile range IQR is the distance between the first and third quartiles:

The first quartile is the median of the observations whose positions in the ordered list are to the left of the location of the overall median. The third quartile is the median of the observations whose positions in the ordered list are to the right of the location of the overall median.

Therefore,
