What else can I help you with?
A trend line on a graph is the same as the line of best fit?
No.
Is a trend line on a graph always the same as the line of best fit?
Usually yes.
In a data plot most of the data points will lie below the line of best fit?
If most of them lie below the line, then that line isn't the best fit. The exact layout depends on what definition you use for "best fit", but any definition will produce a line that has roughly the same number of data points on each side of it.
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.)
A trend line on a graph is the same as the line of best fit?
No.
A trend line on a graph is always the same as the line of best fit?
No.
Is a trend line on a graph always the same as the line of best fit?
Usually yes.
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.
In a data plot most of the data points will lie below the line of best fit?
If most of them lie below the line, then that line isn't the best fit. The exact layout depends on what definition you use for "best fit", but any definition will produce a line that has roughly the same number of data points on each side of it.
What is a line of best fit on a line graph?
The line that minimized the sum of the squares of the diffences of each point from the line is the line of best fit.
What is a line that is not a line but is almost a line?
A line of best-fit.
What is the difference between a trend line and a line of best fit and how are they useful in analyzing data?
What is the difference between a trend line and 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.)
Does the line of best fit have to start from the origin?
The line of best fit does not have to pass through the 0 (origin) and rarely does
What is the process of finding line of best fit called?
Finding the line of best fit is called linear regression.
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
