geom_point()
geom_histogram()
ggplot()
scale_y_log10()
ylab()
facet_wrap()
geom_segment()
xlim()
facet_grid()

(in R code)

Expert Solution

Following functions from the ggplot2 graphics package with the task it performs.

Add each of the following (X, Y) score pairs to the data in the table below. (Add only the single data point in each part of this problem, so that there are always eight scores in the sample.) For each part, sketch a scatterplot of the data with the additional point included and compute the correlation between X and Y with the additional point included. Compare these correlations to the one you computed in section II question #1 above. Note...

For each of the scenarios below construct a decision chart (correct and incorrect decisions) similar to Table 5-3 in the textbook, but be sure to explain what each decision means in terms of your scenario descriptions. In other words, you need to provide me more than simply Type I or Type II error in each cell of the matrix – spell it out in words – at least a sentence or two. a. A study working with premature infants to...
