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

Transcribed Image Text:**Title: Analyzing Teenage Work Habits**
**Introduction:**
This section explores the patterns of teenagers working between the ages of 14 to 18, presented through a double bar chart. The data allows us to evaluate whether age influences the likelihood of teenagers engaging in work activities.
**Graph Description:**
The chart is titled "Students Who Worked Ages 14-18". It features a vertical axis labeled "Number of Students" ranging from 0 to 30 and a horizontal axis labeled "Ages" covering ages 14 to 18.
**Bar Chart Details:**
- Each age group has two bars: one represents students who worked (blue) and the other represents those who did not work (red).
- At age 14, more students did not work compared to those who did.
- Ages 15 and 16 show a balanced number of students working and not working.
- At ages 17 and 18, a significant increase in the number of students working is observed, surpassing those who did not work.
**Discussion:**
The data indicates a trend where older teenagers are more likely to work. However, the chart alone cannot determine causation - it does not definitively show that age causes more teenagers to work.
**Conclusion Question:**
Based on the bar chart, can we conclude causation? (Can we conclude that an increase in age causes more teenagers to work)?
- Options:
- Yes
- No
This exercise helps in understanding correlation and causation in data analysis.
