Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

### Frequency Distribution of Students by Age Group

#### Age Distribution Table

| Ages | Number of Students |
|--------|--------------------|
| 15-18 | 8 |
| 19-22 | 9 |
| 23-26 | 7 |
| 27-30 | 6 |
| 31-34 | 6 |
| 35-38 | 3 |

This table shows the distribution of students across different age groups.

#### Instruction
Based on the frequency distribution above, find the cumulative frequency for the class with the lower class limit of 31.

#### Formula
**Cumulative Frequency** refers to the sum of the frequencies for all classes up to and including the current class.

**Cumulative Frequency** = Sum of the frequencies from the first class up to the class with lower class limit of 31.

Cumulative Frequency (for ages up to 31-34) = Frequency of (15–18) + Frequency of (19–22) + Frequency of (23–26) + Frequency of (27–30) + Frequency of (31-34)

Cumulative Frequency = 8 + 9 + 7 + 6 + 6 = 36

#### Cumulative Frequency Calculation
Enter the cumulative frequency value you have calculated in the box below:

Cumulative Frequency = [ ]
