DATA 311 - Lecture 7 Worksheet

Write the names of the students at your table:

1. A dot plot and a line plot are much the same, except in a line plot you connect the dots (usually with a straight line, though you could use fancier interpolation methods). What factors might you want to consider when deciding between a dot plot and a line plot?

2. Of the ones we’ve discussed so far (table, dot/line, box and whisker), which kind of visualization would you use to illustrate each of the following?

   1. The number of cars per model year in the MPG dataset

   2. The distribution of each penguin body measurement, independent of species.

   3. The summary statistics of each penguin body measurement for each species.

3. Of the ones we’ve discussed so far (table, dot/line, box and whisker, scatterplot, barplot, histogram), which kind of visualization would you use to illustrate each of the following?

   1. Average signal per subject in the fmri dataset.

   2. The signal over time for each event type in patient 0, regardless of region.

   3. The distribution of bill lengths for Adelie penguins.
