 Hello and welcome to this session. In this session we discuss how to graph scatterplot and draw the line of best fit for the given data on the graphing calculator. Let us consider the following data set. Now we will draw its scatterplot on graphing calculator and we will also draw the line of best fit. Firstly we will press mode key and we will get this display. Now scroll down to function and press enter key to set function graphing mode. Now press start and we will get following display. Now we will press number 5 to select setup editor and we get setup editor on screen. Now press enter then is displayed on screen. This removes lists from start list editor columns 1 through 20 and then stores list L1 through L6 in columns 1 through 6. Now again press start and we get the following display. Now press 1 to select edit from menu. We get the following display. The start list editor is displayed. L1 and L2 columns are given. We will store our data in the columns L1 and L2. In L1 enter all the x values from the given data. Now for this write the value 2 and press enter. Now write 4 and press enter and so on. Now scroll to write in column L2 and write all the values given in the data in the similar way. And we get the following display of values on screen. Now press y is equal to key and we get the following display. If any function is written then press clear key to clear all functions. Now press second followed by y is equal to key to get the display of start plot on screen. And we get the following display. Now press number 1 key to select plot 1. Start plot editor is displayed on screen. Press enter to select on which turns on plot 1. Scroll down press enter to select type of display. Here we want scatter plot so we move cursor to image of scatter plot and press enter. Now again scroll down and press second followed by number 1 key because L1 is written above number 1 key. To specify X list L1 for plot 1. Similarly press second followed by number 2 key because L2 is written above number 2 key to specify Y list L2 for plot 1. Now scroll down to select the mark for data points dot plus sign of square. We select plus sign as the mark for each data point by scrolling to plus sign and press enter key. Now press zoom and we get the following display. Scroll down and now press number 9 key to select zoom stat from the zoom menu. The window variables are adjusted automatically and plot 1 is displayed. And this is the scatter plot of the given data. Now let us fit a line to the data for this press that scroll to write stat pel C menu is displayed. Press 4 key to select regression line AX plus B and we get the following display on screen. Now press second L1 followed by comma key and second L2 followed by comma key. Now see L1 and L2 are displayed along with regression line. Now press where key that is variables key and we get the following menu on screen. Now scroll to write while where function is displayed. Now select function by pressing number 1 key and we get this display. Now select Y1 by pressing number 1 key so we get L1, L2 and Y1 displayed on screen. Now press enter to execute linear regression AX plus B we get the following display. The linear regression for the data in L1 and L2 is calculated. The values for A and B are displayed on the home screen. The linear regression equation is stored in Y1. Now press graph the regression line and scatter plot are displayed. Now press press to get the display of the coordinates and points in data set. So here we have got the display of the coordinates and points in the data set. Thus we can draw scatter plot and fit the regression line on graphing calculator. So in this session we have discussed how to graph scatter plot and draw the line of best fit for the given data on the graphing calculator. And this completes our session. Hope you all have enjoyed the session.
