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.

Transcribed Image Text:The image presents a probability density function (PDF) graph. The x-axis is labeled \( x \) and ranges from 1 to 8, while the y-axis is labeled \( P(x) \) and ranges from 0 to 0.35.
The graph features a polygonal shape filled in light blue, extending from \( x = 1 \) to \( x = 5 \):
1. From \( x = 1 \) to \( x = 5 \), the shape forms a triangle with its peak at approximately \( P(x) = 0.35 \) when \( x = 1 \) and tapers down linearly to \( P(x) = 0 \) at \( x = 5 \).
2. Beyond \( x = 5 \), the graph features a small unshaded triangle extending to \( x = 6 \) with a base along the x-axis and its peak at a lower height of \( P(x) = 0.05 \).
This function likely represents a piecewise linear distribution where the total area under the curve sums to 1, aligning with the properties of probability density functions. The shaded area indicates the region of interest within the distribution.
