In a data set with a strong linear correlation, the points in the scatter plot approximate a line. Turn on Show least-squares fit line. The . least-squares fit line. is the “best-fit” line, or the line that most closely “fits” the shape of the data. When r = 1, how are the points in the scatter plot related to the least-squares fit line ...

Then, on a sheet of triangular graph paper, mark the points for each of the Harker triangles and connect them with the line (equivalent to the extension from point #2 through point #1). Use the point of mutual intersection of these lines to determine the percentages of olivine, plagioclase, and augite in …

Once you have written the r value written down, press zoom 9 to graph. 1. Record the value of r. 2. Draw a scatterplot for each. 3. For each graph, draw a line of best fit. 4. For each graph, write a sentence describing how closely the data points relate . to the line of best fit. 5. What is the connection between the sign of . r. and the slope ...

Therefore, a straight-line graph should result. Now determine the slope of the line. Since R= L/A, the slope of a graph of R vs. L is /A. C. The relationship between resistance and width. 3. Draw a line about 8-mm wide and 5-cm long. Draw a second line below it about 4-mm wide and 5-cm long.

For many locations, a scale where each line on the x-axis represents one day and each line on the y-axis represents 1/2 meter will work well. Now you are ready to plot your data. First plot the height of the first high tide of the month. Then skip the next high tide and plot the …

A line graph is simply the next step in a scatter plot and is drawn by connecting the data points represented in the scatter plot according to the order of the independent variable. When looking at line graphs we can begin to see patterns in our data.

Plot a graph of. R. against 1/ I. Draw the best possible straight line through the points (they might be quite scattered) in Excel, put the equation of the line on the graph. The gradient of this graph is the emf of the cell. The negative intercept on the y-axis is the internal resistance.
