1 SCATTER PLOTS. Presented by Andrew Crosby, Dominique Brown, and Veronica Coronado a. Compare and contrast two scatter plots through DOFS, using comparing words and phrases. b. Explanatory & response variables

2 Scatterplot description terms D - Direction/Trend Positive or Negative O – Outliers Data Point(s) far from other data F – Form/Shape Linear, Curved S – Strength/Spread The closer the data points the stronger the description Additional information on Scatterplots Ordered Pair/Bivariate Data Scatterplots show relationship between two quantitative variables measured on the same individual object

3 SCATTER PLOTS: DOFS Compare and contrast two scatter plots through DOFS, using comparing words and phrases D: Positive or Negative O: Does any point fall outside the overall patters? F: Linear? Curved? Cluster? Gaps? S: Strong, Weak, or Moderate?

4 SCATTER PLOTS: DOFS Compare and contrast two scatter plots through DOFS, using comparing words and phrases. D: Positive or Negative O: Does any point fall outside the overall patters? F: Linear? Curved? Cluster? Gaps? S: Strong, Weak, or Moderate?

5 The D in DOFS stands for data a. T b. F Scatterplots are ordered pairs, or bivariate data a. T b. F A scatterplot shows the relationship between… a. Qualitative variables b. Quantitative variables

6 Explanatory & Response Variables *Response Variable; Often called a dependent or predicted variable is normally on the Y axis, and considered the Y variable *Can be a different measurement than X variable *Explanatory Variable ; Often called an independent or predictor variable, is normally on the X axis, and is considered the X variable *Can be different measurement than Y variable

7 1. If Age is the Explanatory, what COULD the response be a. Lipstick Color b. Eye Color c. walk rate d.how many pets they have 2. If the measurements for the x axis is feet, the y axis can be yards. a. true b.false 3, Match the variable to its normal axis a. y variable 1. horizontal b. x variable 2. vertical
