When the links between these concepts are revealed, one arrives at a relational understanding of the line of best fit
in the least squares sense.
In addition, a Regression Analysis was performed to look for trends in the line of best fit
for each Process Standard.
Using a popular shareware program for fitting curves by LSR (CURVEFIT, 1988), the curved line of best fit
After 8 scores were collected, if the line of best fit
was flatter than the goal line, the teacher introduced a teaching change to improve the rate of progress, and collected 8 new scores.
The next step is to describe a line, called the "line of best fit
," drawn through the data.
They joined the data points with simple curves and also drew an approximate line of best fit
that they thought best fits the data.
Use the spreadsheet to fit a straight line of best fit
to the data points and find the equation of the line of best fit
Regression analysis of the data yielded the equation for the line of best fit
as: MEIA = 1.39 ([+ or -] 0.04) X HPLC-MS + 1.30 ([+ or -] 0.46) [micro]g/L (r = 0.951; [S.sub.y|x] = 2.46; n = 125).
(Rather than connecting the data points, scientists sometimes draw a line of best fit
, which shows the general trend the data follow.
On top of each I have superimposed a line of best fit
- the curve that captures most accurately the underlying trend.
Then using the resulting line of best fit
(regression line), they determine the apparent molecular weight of unknown proteins based on their mobility during gel electrophoresis.
