What is the relationship between the $$\$ $$ price of paint and the gallon demand for this paint? A random sample of (price, quantity) data for 7 days of operation was obtained. Construct a plot and describe the relationship between quantity and price, with emphasis on any unusual observations. $$ \begin{aligned} & (10,100)(8,120)(5,200)(4,200)(10,90) \\ & (7,110)(6,150) \end{aligned} $$

Key Concepts

Outlier Analysis

Outlier analysis involves identifying data points that deviate markedly from the pattern observed in the rest of the data. Outliers can provide insights into unusual operational conditions, errors in data collection, or unique market behaviors that may need further investigation.

Demand Analysis

Demand analysis studies consumer behavior in response to price changes, evaluating how variations in price can influence the quantity of a product demanded. It is fundamental in understanding market dynamics and in making pricing decisions.

Scatter Plot

A scatter plot is a graphical representation used to display the relationship between two quantitative variables by plotting data points on a two-dimensional plane. It allows for visual inspection of trends, patterns, or anomalies within the dataset.

Correlation

Correlation refers to the statistical association and degree of linear relationship between two variables. In the context of price and demand, it typically examines whether a change in price is associated with an increase or decrease in the quantity demanded, often expecting that higher prices lead to lower demand.
