If you to try to follow along, the data can be foun. Please see the TI-Nspire CX CAS and TI-Nspire CAS guidebooks for additional information. This video will show you how to create a scatter plot and best-fit line using your TI Nspire Calculator. The answers show the y coordinates for the two critical points on this function. For example, the second screen shows the variable stat.resid pasted to the entry line. keys, you can scroll through this list and paste a variable into the entry line on the Calculator page. To view this list, add a Calculator page and press VAR. Now to solve for the additional points, plug x into the original equation: A variety of variables (26 in all) are stored by TI-Nspire after a regression. Since there are two answers for the following function, there will be two sets of critical points on this function. To find one of the critical points the user will need to set the derivative (shown above) equal to zero and solve for x:Ģ) Press. The first step to finding the critical points is to differentiate the above function:ġ) Press and choose to add a Calculator.ĥ) Press. The following illustrates how to use the differentiate and solve functions to find critical points.Įxample: Find the critical points using the solver and differentiation commands on the home screen for the following function: The critical points of a function are the points where the derivative is equal to zero, reach a local minimum, or reach a local maximum. How can critical points be found using the TI-Nspire CAS family? See this article for a full explanation on producing a plot from a spreadsheet table.Solution 35314: Finding Critical Points Using the TI-Nspire™ CAS Family. This type of chart can be used in to visually describe relationships ( correlation) between two numerical parameters or to represent distributions.Įxcel is often used to generate scatter plots on a personal computer. Each x/y variable is represented on the graph as a dot or a cross. What is a scatter plotĪ scatter plot (or scatter diagram) is a two-dimensional graphical representation of a set of data. To clear the scatter graph and enter a new data set, press "Reset". calculate and graph a quadratic regression on the TI-Nspire Family Products. A scatter plot (or scatter diagram) is a two-dimensional graphical representation of a set of data. Plot the regression equation along with the scatter plot. To clear the scatter graph and enter a new data set, press 'Reset'. The problem is the teacher taught everyone how to do it on a different TI calculator, so if anyone knows how to do this on the TI-nspire CX, I would very much appreciate it. 13) Scroll down to Xlist and press 2nd 1 to input L1. Hello guys, I’m in adv algebra II, and for my homework I need to graph scatter plots and then find the linear regression line. In this video, learn how to create a scatterplot on the TI-Nspire graphing. and press ENTER to select the scatter plot option. 41K views 11 years ago TI-Nspire Mini-Tutorials. TI-84 Plus Family Graphing Calculator, and TI-Nspire Handheld in TI-84 Plus Mode. To clear the graph and enter a new data set, press "Reset".įor the scatter plot to be displayed the number of x-values must equal the number of y-values. For the scatter plot to be displayed the number of x-values must equal the number of y-values. TI-84 Plus CE Apps and Updates TI-Nspire CX Updates All software, OS and Apps Activities.b) Would you buy the brand represented by (31, 4) or the one by (32, 34) Explain your answer. a) Estimate the highest rating for any of the brands. In this tutorial, you will learn how to graph a scatterplot using the TI-Nspire CX. Press the "Submit Data" button to perform the computation. A scatter plot of paired measurement variables can often be described in terms of clusters, gaps, and unusual data points.This flexibility in the input format should make it easier to paste data taken from other applications or from text books. Individual values within a line may be separated by commas, tabs or spaces. Individual x, y values (again, separated by commas or spaces) on each line. Data can be entered in two different formats:Ĭomma or space separated x values in the first line and comma or space separated y values in the second line, or. Enter the x and y data in the text box above.Use this page to generate a scatter diagram for a set of data:
