To create contrast when choosing two colors, pick them Correct Ans-From opposite sides of
the color wheel
Which color is most strongly perceived by your brain? Correct Ans-Green
Used for common continuous variables that vary from low to high. Correct Ans-Sequential
Maps only to variables of a nominal type, i.e. not continuous. It gets cluttered and confusing to
use too big a palette (too many colors) at a time. Correct Ans-Qualitative
Used for variables that have values with two separate extremes and neutral ground in
between. Correct Ans-Divergent
When creating a sequential color palette, pay most attention to varying the: Correct Ans-
Lightness/Value
Colorblind People Correct Ans-may be completely unaware of data distinctions drawn with
certain palettes.
, To create a palette where there is a large difference between the two ends, use colors close to
____ sides of the color wheel. If there is just a subtle difference from one end of the spectrum to
the other, use colors that are close to _____ on the color wheel. Correct Ans-opposite;adjacent
Select all of these that are appropriate uses of color on maps: Correct Ans-1. Show values of
continuous data, one carefully colored pixel per location
2. Show different types of terrain, e.g. different color for water vs. trees vs. dessert.
3. Encode topological information, like height above sea level at each pixel
4. Annotate with categorical color-coded information, like blue lines for cold fronts on weather
maps.
An exponential function f(x) is one of the form: Correct Ans-a*n^x
Suppose the values for some variable X are in the range 10 million to 100 million dollars. Using
the axis label "Log of Dollars" vs. "Log of Millions of Dollars" means Correct Ans-shifting
the scale by an offset
A Tukey Box Plot can be used to show values with uncertainty, i.e. sampled from a distribution.
Besides showing the median, it shows context by indicating Correct Ans-1. The outliers
plotted as points
2. One quartile on either side of the median.
A violin plot with data plotted as dots within the 'violin' area is called Correct Ans-Bean Plot
