Answer to Problem 2CFU
- Draw
- Predict an equation
- Find regression line
Explanation of Solution
Given information:
Methods of best fit line for a set of data
Calculation:
Method 1: Draw
Plot all the known points onto the graph paper and draw a line that best represents the set of data. Use a pencil or a line tool to literally hand-draw the best fit line.
Method 2: Prediction of equation.
Choose two points that best represents the set of data. Put the
Then put both the values m and b into the slope-intercept formula to create a prediction equation for the best fit line.
Method 3: Find the regression line
Put all the point values into the equation calculator for regression line and hit enter.
