Task goals
- Recall what T, A, R, S, O, and G each stand for in the TARSOG framework for scatter plots.
- Identify the trend in a scatter plot as linear or non-linear.
- Identify the association as positive or negative (correlation direction is correctly described as positive/negative for scatter plots, unlike time series trend).
- Judge the relationship strength as weak, moderate, or strong from how closely points cluster around the trend.
- Identify the scatter as constant or non-constant (whether the spread of points stays even or changes across the plot).
- Identify outliers and groupings, and explain how each affects the reading of the overall trend and association.
- Analyse an unfamiliar scatter plot using all six TARSOG components together, justifying each classification.

Know
In relationship investigations: sometimes one variable is thought of as predictive of the other variable; then the response or dependent variable is on the y-axis, and the 'predictive', explanatory, or independent variable is on the x-axis; an eyeballed line or curve of best fit can be added for paired numerical data.
