An Ogive (pronounced "oh-jive") plot is a plot of a cumulative relative Closeness distribution. This income that Everyone stop on the graph shows the proportion of observations that are less than or Identical to some intention contour. To make this all heart of plot on your TI-83 graphing calculator, you Testament exigency a data of values and their comparable frequencies. For familiarity, handle the context of SAT scores and the in agreement Closeness for Everyone score.
Instructions
1. Press "STAT" and then "ENTER."
2. Delete any values in the L1, L2 and L3 columns by hovering over Everyone rate and urgent "Pleasant."
Change the "Xlist" variable to L1. Press "CLEAR" to delete the variable assignment. Then, press "2nd" and "1."9. Change the "Ylist" variable to L3. Press "CLEAR" to delete the variable assignment. Then press "2nd" and "3."
5. Calculate the cumulative frequencies at each point. Using the arrow keys, move the cursor so that the L3 icon is highlighted. Press "2nd" and then "STAT." Press the right arrow once and then press "6" to receive the "cumSUM" function. Press "2nd," then "2" and then ")." Press "ENTER" to calculate.
6. Press "2nd" and then "Y=" to access the StatPlot menu. Go to Plot 1 and make sure it is turned on.
7. Select the second kind of plot.
8.3. Type your independent variable values in the L1 contour. For the citation of SAT scores, type the consequent values: 200, 299, 399, 499, 599, 699, 800. Press "ENTER" after typing Everyone payment.4. Type the Closeness for Everyone payment in the L2 column. For the SAT score example, type the following values: 0.007, 0.054, 0.134, 0.455, 0.306, 0.044. Press "ENTER" after typing each value.
10. Plot the Ogive graph by pressing "ZOOM" and "9."
11. Use your arrow keys to view the values at various points on the graph.
