Is the best fit line the same as the line of best fit?
Yes but phrased differently
What is a line that is not a line but is almost a line?
A line of best-fit.
Why does best fit line does not touch all data points?
Because the "best fit" line is usually required to be a straight line, but the data points are not all on one straight line. (If they were, then the best-fit line would be a real no-brainer.)
What is the process of finding line of best fit called?
Finding the line of best fit is called linear regression.
What is a best-fit-line?
A best-fit line is the straight line which most accurately represents a set of data/points. It is defined as the line that is the smallest average distance from the data/points. Refer to the related links for an illustration of a best fit line.
Which is the best equationof a line of best fit this scatterplot?
A straight line equation
Why you call regression line as line of fit?
It is called the line of best fit because it tends to satisfy all the possible points in consideration at the same time with minimal variation.
What are two reasons for all the points not been on a line of best fit?
A line of best fit is used to create an image of the overall correlation between two factors on a scatter graph (showing the general shape of the graph). As a line of best fit should be either a straight line or a smooth curve, the line visiting every point would be impossible to retain this shape (as the experimental results will likely not be identical to the theoretic ones). Also, a line of best fit can be used to highlight anomalous results, so the whole point of it would be destroyed if every point was visited anyway.
What points must the line of best fit go through?
As many as possible
Can you make a linear equation from a nonlinear table?
Using the line of best fit, yes.
How do you find a y-intercept of a scatter plot?
You have to put a line of best fit onto the graph and find where that line crosses the y-axis.
Is it true in a perfect relationship all point of a scatter plot fall on a line?
Yes if all points are on the same line of best fit
What does line of best fit mean?
Usually when there's 2 dots(data points), you can place a line.When there's more data points, there's way to calculate "best line" that reduces error to the minimum. So kind line best choice of approximate line that defines these dots.
Is the best-fit line helpful in estimating vaules of data points true or false?
Yes. (True)
What do the lines above the best fit line represent?
The lines above represent nothing other than invisibility!
What would you employ to know if there is a statistically significant difference between the means of two groups?
A bar chart, line graph or a scatter gram for the line of best fit
Can you have a correlation of 1.03?
I'm not sure that I have the right understanding for the question but it seems to fit. If you are talking about the r^2 value, correlation of a line of best fit, then it should not be over 1.
