Understanding the Two-Way Table: A Case Study at the Kansas City Airport

In the world of statistics and data analysis, two-way tables are a crucial tool for understanding complex relationships between variables. A two-way table is a table that displays the frequency distribution of two categorical variables. In this article, we will explore a real-life scenario where a group of pilots from Skyways and Yellow Jet airlines were asked about the direction of their flights. The two-way table shows their answers, and we will delve into the discussion category of mathematics to understand the underlying concepts.

The two-way table shows the answers of the pilots from Skyways and Yellow Jet airlines about the direction of their flights. The table is as follows:

	East	West
Skyways	15	10
Yellow Jet	8	12

To understand the two-way table, we need to interpret the data. The table shows the frequency distribution of two categorical variables: the airline (Skyways or Yellow Jet) and the direction of the flight (East or West). The numbers in the table represent the number of pilots who answered that their flights were flying in a particular direction.

Calculating the Total Number of Pilots

To calculate the total number of pilots, we need to add the frequencies of both airlines for each direction. For example, the total number of pilots who answered that their flights were flying East is 15 (Skyways) + 8 (Yellow Jet) = 23. Similarly, the total number of pilots who answered that their flights were flying West is 10 (Skyways) + 12 (Yellow Jet) = 22.

Calculating the Row and Column Totals

To calculate the row and column totals, we need to add the frequencies of each row and column. For example, the total number of pilots from Skyways is 15 + 10 = 25. Similarly, the total number of pilots from Yellow Jet is 8 + 12 = 20.

Calculating the Marginal Totals

To calculate the marginal totals, we need to add the frequencies of each row and column. For example, the total number of pilots who answered that their flights were flying East is 15 (Skyways) + 8 (Yellow Jet) = 23. Similarly, the total number of pilots who answered that their flights were flying West is 10 (Skyways) + 12 (Yellow Jet) = 22.

Calculating the Conditional Probabilities

To calculate the conditional probabilities, we need to divide the frequency of each cell by the marginal total of the corresponding row or column. For example, the probability that a pilot from Skyways answered that their flight was flying East is 15/25 = 0.6. Similarly, the probability that a pilot from Yellow Jet answered that their flight was flying West is 12/20 = 0.6.

Calculating the Joint Probabilities

To calculate the joint probabilities, we need to divide the frequency of each cell by the total number of pilots. For example, the probability that a pilot answered that their flight was flying East and they were from Skyways is 15/45 = 0.3333. Similarly, the probability that a pilot answered that their flight was flying West and they were from Yellow Jet is 12/45 = 0.2667.

In conclusion, the two-way table shows the answers of the pilots from Skyways and Yellow Jet airlines about the direction of their flights. By interpreting the table, we can calculate the total number of pilots, row and column totals, marginal totals, conditional probabilities, and joint probabilities.
