What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional grid.

What does it mean if a point is an outlier in a scatter plot?

Back

An outlier is a data point that differs significantly from other observations in the dataset, often lying outside the overall pattern of the scatter plot.

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, used to make predictions about future data points.

Front

How do you determine if a line is a good line of best fit?

Back

A good line of best fit minimizes the distance between itself and all the data points, ideally passing through the center of the data distribution.

Front

What is the purpose of using a scatter plot?

Back

Scatter plots are used to visualize the relationship between two variables and to identify trends, correlations, or patterns in the data.

What does it mean to make predictions using a line of best fit?

Back

Making predictions using a line of best fit involves using the equation of the line to estimate the value of one variable based on the value of another.

Front

What is the range in a set of data?

Back

The range is the difference between the highest and lowest values in a dataset.

What is the median in a set of data?

Back

The median is the middle value when a dataset is ordered from least to greatest; if there is an even number of observations, it is the average of the two middle values.

Front

How can you identify trends in a scatter plot?

Back

Trends in a scatter plot can be identified by observing the direction of the data points; a positive trend shows an upward slope, while a negative trend shows a downward slope.

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a linear relationship between two variables, which can be positive, negative, or none.
