Graphing Calculator Practice
Practice graphing calculator skills in Grade 10 math. Enter data sets, configure STAT PLOT with swapped axes, plot scatter plots with regression lines, and interpret visual results.
Key Concepts
Combine your skills to plot new data sets with a twist. After entering the data into L1 and L2, configure the STAT PLOT to use L2 as the Xlist ($x$ values) and L1 as the Ylist ($y$ values). This allows you to analyze the relationship between the data sets from a different graphical perspective.
Enter the data set {5, 4, 4, 5, 5, 4, 4} into list L1. Then, enter the corresponding data set { 8, 6, 5, 2, 1, 3, 6} into list L2. In [STAT PLOT], set Xlist to L2 and Ylist to L1 to create a scatter plot with the axes swapped as requested.
Time to put your skills to the test! This is about applying what you've learned: entering new data and then graphing it. The key challenge here is to swap the axes, making your second list (L2) the $x$ values and your first list (L1) the $y$ values. It’s a great way to see data from a different perspective!
Common Questions
How do you set up a STAT PLOT with swapped x and y lists?
Enter data in L1 and L2. Go to STAT PLOT, turn Plot1 on, set Type to scatter. Set Xlist to L2 and Ylist to L1 to swap which data appears on each axis.
How do you run a regression and graph the line on a scatter plot?
After entering data, run LinReg from STAT CALC. Store the result in Y1 by pressing Y-VARS. Enable STAT PLOT for the scatter. Press ZOOM, select ZoomStat to auto-fit the window, then GRAPH.
What is ZoomStat on a graphing calculator?
ZoomStat automatically adjusts the viewing window to show all entered data points. It prevents having to manually set Xmin, Xmax, Ymin, and Ymax, saving time when plotting data sets.
