Q 1.3. - The Practice of Statistics for AP

Question

Here, once again, is the stem plot of travel times to work for $20$ randomly selected New Yorkers. Earlier, we found that the median was $22.5$ minutes.

Interpret your result from Question 2 in context without using the words “mean” or “average".  

Step-by-Step Solution

Answer

In case one effectively divided the time of travel among $20$ people, everyone will have $31.25$minutes time of travel.

Step 1: Given information

As per the provided information, the Median is$22.5$ minutes.

The number of observations :$20$

Step 2: Concept

The data is divided into stems (the highest digit) and leaves (the lowest digit) in a stem and leaf plot (the smallest digits). Before the personal computer, they were popular because they were a quick way to sketch data distributions by hand. When objects need to be displayed in a way that demonstrates the hierarchical structure as well as amount or size, pyramid charts are the ideal choice. This can include positions in management, items sold, and business locations, among other things

Step 3: Explanation

The following is an example of how to evaluate conclusions based on the data from the previous question without using the words "average" or "mean":

Everyone will have $31.25$ minutes of travel time if the journey time is effectively shared among $20$ people.
