What does account for any deviations in your data from the best-fit line in concrete terms mean?
It means that you need to give reasons why every point was not on the best fit line.
How do you graph the direct relationship?
you draw the line of best fit
Why is a best fit line used to find slope instead of using the data points?
Because the data points are generally not all in line with each other. If you connect the dots,from one data point to the next and then to the next, you usually get a zig-zag line of manysegments, where the slopes of the segments are all different and cover a wide range. It wouldbe impossible to decide what the "real" slope of the data is. The "best fit" line is a line that findsthe pattern buried in the zig-zag data, giving each data point its best share of determining the bestsingle equation to represent the whole batch of points. That's why it's called "best".
How would you describe the slope of a graph showing slow speed?
Im guessing that this is a distance over time graph. if so, the gradient of the line of best fit would have a low value. (not be very steep)
What scientist would best fit this scene?

What is a line of best fit?
A line of best fit is a technique used in statistics. It is a line that represents the relationship between data points showing two variables. It is "best" according to some user-specified criteria. The least squares regression line is the most popularly used line of best fit but it is not the only option.
Why does the line of best fit have to start from 0?
The line of best fit does not have to start from 0.
Is the best fit line the same as the line of best fit?
Yes but phrased differently
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.
How can a line of best fit be useful?
It is very useful and interesting to be able to enter data for two variables, graph those points in a scatter plot, and then generate a line of best fit through those points. From the line of best fit, it is fairly simple to generate a linear equation. A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions.
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 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
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.
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.
How relevant is linear equation to a firm?
The line of best fit is used to predict future decisions.
