Introduction
Research on the topic, Background/related information. (No analysis on this
slide.)
Provided scatterplot of data identifying explanatory and response variable
with no regression curve on scatterplot
Linear Section
Provided a scatterplot with the line on graph. Provided the linear equation along
with Se and r2. Discuss the association, if any.
Provided the residual plot and interpret meaning.
Provided analysis of the correlation coefficient, r and whether direction was
positive/negative.
Talked about the slope as a rate of change including units, and interpreted what
it means in context of the data.
Talked about the y-intercept and interpreted what it means in the context of the
data.
Non-Linear Model Quadratic Function
Provided a scatterplot, with the correct regression curve on the graph. Provided
the regression equation along with Se and r2.
Provided the residual plot and interpret meaning.
Best Fit
Provided a comparison table with the model type, residual plot description, r 2
and Se
Provided a slide with the two residual plots and discussed which one was the
best in terms of randomness.
Concluded which of the two models was the best and explained why.
Interpreted SE and r 2 for the best fit model only in context.
Conclusion
Discussed whether the best fit is appropriate for use in making predictions.
Spoke of something they learned from this data analysis or from the topic in
general. Talked about why this information is important, who can benefit from
this data.
