1. 1

   A scatter diagram, also known as a scatter plot, X-Y graph, or correlation chart, is used to graph pairs of numerical data to identify potential relationships between them.

2. 2

   When using a scatter diagram, if the variables are correlated, the points will generally fall along a line or curve, and the stronger the correlation, the tighter the points will hug the line.

3. 3

   In Excel, to create a scatter diagram, you must first select the data, then go to the Insert tab, click on the Charts group, and select Scatter to choose the desired scatter chart type.

“An ice cream shop recorded the number of ice cream cones sold and the high temperature for 10 days. Create a scatter plot using the data below. Describe the type of correlation shown in the scatter plot. Day 1: 80°, 20 cones Day 2: 75°, 15 cones Day 3: 90°, 30 cones Day 4: 65°, 10 cones Day 5: 85°, 25 cones Day 6: 70°, 12 cones Day 7: 95°, 35 cones Day 8: 60°, 8 cones Day 9: 82°, 22 cones Day 10: 88°, 28 cones”
