Which line represents the line of best fit for the scatter plot data?

The red line represents the line of best fit for the scatter plot.

What line is best for a scatter plot?

line of best fit
A line of best fit is a straight line drawn through the maximum number of points on a scatter plot balancing about an equal number of points above and below the line.

What does the best fit line tell you?

The line of best fit , also called a trendline or a linear regression, is a straight line that best illustrates the overall picture of what the collected data is showing. It helps us to see if there is a relationship or correlation between the two factors being studied.

How do you find the line of best fit for data?

The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.

Which line represents the best fit?

Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points.

What does the line of best fit tell you?

What is the slope of the line of best fit?

The line’s slope equals the difference between points’ y-coordinates divided by the difference between their x-coordinates. Select any two points on the line of best fit. These points may or may not be actual scatter points on the graph. Subtract the first point’s y-coordinate from the second point’s y-coordinate.

Why is it called the line of best fit?

The regression line is sometimes called the “line of best fit” because it is the line that fits best when drawn through the points. It is a line that minimizes the distance of the actual scores from the predicted scores.

Which of the following is the preferred model to find the best fit line?

The least-square error is the preferred model to the best fit line data set using linear regression. Explanation: The regression line is chosen using the least-squares criterion.

What is meant by the line of best fit quizlet?

A line of best fit (or “trend” line) is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.

How to find the line of best fit?

Calculate the mean of the x -values and the mean of the y -values.

  • The following formula gives the slope of the line of best fit: m = ∑ i = 1 n ( x i − X ¯) ( y i
  • Compute the y -intercept of the line by using the formula: b = Y ¯ − m X ¯
  • Use the slope m and the y -intercept b to form the equation of the line.

    • What is an example of a line of best fit?

    A line of best fit (or “trend” line) is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points. Example: Is there a relationship between the fat grams and the total calories.

    What is the strength of a scatter plot?

    Strength refers to the scatter of the plot: if the points are tightly concentrated around a line, the relationship is strong. Scatter plots can also show unusual features of the data set, such as clusters, patterns, or outliers, that would be hidden if the data were merely in a table.
