Understanding the Two-Way Table

A two-way table is a statistical tool used to display the relationship between two categorical variables. In this case, the two-way table is used to show the number of viewers who rated a film on a four-point scale: excellent, good, average, and poor. The table is divided into two main categories: the viewer's age group and the discussion category, which in this case is mathematics.

The Importance of Two-Way Tables in Statistics

Two-way tables are an essential tool in statistics, as they provide a clear and concise way to display the relationship between two categorical variables. By using a two-way table, researchers and analysts can easily identify patterns and trends in the data, which can be used to make informed decisions. In this case, the two-way table is used to display the number of viewers who rated the film on a four-point scale, which can be used to identify the most popular rating categories among different age groups.

The Columns in the Two-Way Table

The columns in the two-way table indicate the numbers of viewers who rated the film on a four-point scale: excellent, good, average, and poor. The columns are labeled as follows:

Excellent: This column shows the number of viewers who rated the film as excellent.
Good: This column shows the number of viewers who rated the film as good.
Average: This column shows the number of viewers who rated the film as average.
Poor: This column shows the number of viewers who rated the film as poor.

The Rows in the Two-Way Table

The rows in the two-way table indicate the viewer's age group. The rows are labeled as follows:

18-24: This row shows the number of viewers who rated the film in the 18-24 age group.
25-34: This row shows the number of viewers who rated the film in the 25-34 age group.
35-44: This row shows the number of viewers who rated the film in the 35-44 age group.
45-54: This row shows the number of viewers who rated the film in the 45-54 age group.
55-64: This row shows the number of viewers who rated the film in the 55-64 age group.
65+: This row shows the number of viewers who rated the film in the 65+ age group.

Interpreting the Two-Way Table

To interpret the two-way table, we need to look at the numbers in each cell. The numbers in each cell represent the number of viewers who rated the film in a particular age group and with a particular rating. For example, the number in the cell where the row is 18-24 and the column is Excellent represents the number of viewers who rated the film as excellent in the 18-24 age group.

Calculating the Total Number of Viewers

To calculate the total number of viewers, we need to add up the numbers in each column. This will give us the total number of viewers who rated the film in each rating category.

Calculating the Percentage of Viewers

To calculate the percentage of viewers who rated the film in each rating category, we need to divide the number of viewers in each category by the total number of viewers and multiply by 100.

Conclusion

In conclusion, the two-way table is a powerful tool used to display the relationship between two categorical variables. By using a two-way table, researchers and analysts can easily identify patterns and trends in the data, which can be used to make informed decisions. In this case, the two-way table is used to display the number of viewers who rated the film on a four-point scale, which can be used to identify the most popular rating categories among different age groups.

Conclusion

The columns in the two-way table indicate the numbers of viewers who rated the film on a four-point scale: excellent, good, average, and poor.

Viewer's Age Group	Excellent	Good	Average	Poor
18-24	10	20	30	40
25-34	15	25	35	45
35-44	20	30	40	50
45-54	25	35	45	55
55-64	30	40	50	60
65+	35	45	55	65

The rows in the two-way table indicate the viewer's age group.

Viewer's Age Group	18-24	25-34	35-44	45-54	55-64	65+
Excellent	10	15	20	25	30	35
Good	20	25	30	35	40	45
