2 When a histogram shows a long tail with a handful of outliers, we say the distribution is skewed because deviates from the ___ distribution.
3 Which unsupervised map classification method in ArcGIS Pro will usually provide you with the best results?
- Defined interval
- Equal interval
- Natural breaks
- Manual breaks
4 Supervised classification methods are always better than unsupervised because humans are smarter than computers. [T/F]
5 Unsupervised classification methods require no input from the user, the computer does all the work. [T/F]
6 Briefly, explain the differences between Supervised and Unsupervised classification methods.
7 Random forests require a user to provide ___ classes.
8 It is important to avoid using sequential color pallets or graduated symbols for _____ data because they can imply a ranking/direction, even though this type of data has no rank/direction.
9 Diverging color maps are great for showing deviations from a mean value. [T/F]
10 Sequential color maps use gradations of different shades (light/dark) of the same color. [T/F]
11 The best maps pack the most amount of information into the least amount of space. [T/F]

- Correctly Calculate
17 What was the reasoning behind Stats Canada updating from the old Rural/Urban to the Population Centre and Rural Area classification method?
18 The Select by __ tool lets us use SQL (Structured Query Language) to define expressions for querying vector data.

- Large Urban Population Centre
- Rural
- Small Population Centre
- Medium Population Centre
21 What percent of BC’s overall population lives in Rural Areas? Round your answer to the nearest percent. Hint Sum the four classes to get the total population.
22 What is the median value for the percentage of income that people in Rural areas spend on food? Round to the nearest tenth percent.
23 How does classifying the data help us reveal patterns compared to what we see in the scatter plot? Does the r2 score indicate a relationship in the scatter plot? What conclusions can you draw about the proportion of income spent on food by people in different regions from looking at the box plot?
