Line of Best Fit.

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatter plot, showing the trend of the data points.

Front

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

Back

A line is an accurate line of best fit if it minimizes the distance between itself and all the data points, ideally capturing the overall trend.

Front

What does it mean if there is no line of best fit for a scatter plot?

Back

If there is no line of best fit, it means that the data points do not show a clear trend or relationship.

Front

What types of associations can be represented in a scatter plot?

Back

Scatter plots can show positive, negative, or no association between variables.

Front

What is a positive association in a scatter plot?

Back

A positive association occurs when, as one variable increases, the other variable also increases.

Front

What is a negative association in a scatter plot?

Back

A negative association occurs when, as one variable increases, the other variable decreases.

Front

What does 'none' indicate in terms of association in a scatter plot?

Back

'None' indicates that there is no discernible relationship or trend between the variables represented in the scatter plot.

Front

How can you visually identify the line of best fit on a scatter plot?

Back

The line of best fit can be visually identified as the line that passes through the center of the data points, balancing the distances to the points above and below it.

Front

What is the purpose of the line of best fit in data analysis?

Back

The purpose of the line of best fit is to summarize the relationship between two variables and to make predictions based on that relationship.

Front

What is the difference between a trend and a line of best fit?

Back

A trend refers to the general direction in which data points are moving, while the line of best fit is a specific line that quantifies that trend.
