Key Concepts

Scatter Plot

A scatter plot is a type of graph that shows the relationship between two numerical variables by displaying data points on a two-dimensional plane. It helps visualize trends, patterns, and potential correlations between variables, allowing comparisons and predictions based on the data distribution.

Correlation

Correlation refers to the association between two variables. In the context of a scatter plot, a positive correlation means that as one variable increases, the other variable tends to increase as well. Understanding this relationship helps in predicting one variable based on changes in the other.

Data Estimation

Data estimation involves making informed guesses about unknown values using available data. With scatter plots, interpolation is used when predicting values within the range of the existing dataset by analyzing the trend of the data. This approach helps in estimating a reasonable study time or score based on the identified relationship between the variables.
