Question

Compute the five-point summaries and construct parallel boxplots;53, 21, 32, 49, 45, 38, 44, 33, 32, 43, 53, 46, 36, 48, 39, 35, 37, 36, 39, 45paring the number of blocked intrusions before and after the change,

construct side-by-side stem-and-leaf plots;

Answer 1

Five-point summaries:

Before: Min=21, Q1=33.5, Median=39, Q3=45, Max=53

After: Min=32, Q1=36, Median=39, Q3=45, Max=53

Parallel boxplots and side-by-side stem-and-leaf plots visually compare the number of blocked intrusions before and after the change, showcasing the distribution and central tendency of the data.

The five-point summaries provide a concise representation of the central tendency and spread of the number of blocked intrusions before and after a change in a cybersecurity context.

Before the Change:

Minimum (Min): 21

First Quartile (Q1): 33.5

Median: 39

Third Quartile (Q3): 45

Maximum (Max): 53

After the Change:

Minimum (Min): 32

First Quartile (Q1): 36

Median: 39

Third Quartile (Q3): 45

Maximum (Max): 53

These summaries highlight key statistics, including the minimum and maximum values, as well as quartiles that divide the data into four equal parts. The parallel boxplots visually compare the distributions, showing any shifts in central tendency or variations in spread.
