the necessary steps to predict data not included in a data set using a scatter plot and line of best fit are Options 2, 3, 4
- Graph the data in a scatter plot
- Extend the line of best fit beyond the data
- Find the average of the data
Steps involved in predicting data
In using the line of best fit also known as the slope, they following steps are involved;
- Draw the line of best fit
- Find the direction of association between the two variables
In using scatterplot, they following steps are involved;
- Draw line of best fit that passes close to most of the data points
- Approximately half of the data points should be below the line and half of the points above the line
This explains that the average of the set of data is found from the scatter plot and line of best fit.
Thus, the necessary steps to predict data not included in a data set using a scatter plot and line of best fit are Options 2, 3, 4
Graph the data in a scatter plot
Extend the line of best fit beyond the data
Find the average of the data
