Question 7A data analyst creates a scatterplot where the points are very crowded, which makes it hard to notice when points are stacked. What change can they make to their scatter plot to make it easier to notice the stacked data points?1 pointChange the shape of the pointsChange the color of the pointsChange ggplot() to ggplot2()Change geom_point() to geom_jitter()

Question 7A data analyst has a scatter plot with crowded points that make it hard to identify a trend. What geometry function can they add to their plot to clearly indicate the trend of the data?1 pointgeom_jitter()geom_smooth()geom_alpha()geom_bar()

What is the primary purpose of a scatter diagram?To calculate the mean of dataTo visualize the relationship between two variablesTo determine the mode of dataTo rank the data points

Question 9A data analyst creates a scatterplot. The analyst wants to put a text label on the plot to call out specific data points. What function does the analyst use?1 pointThe annotate() function The ggplot() function The facet_grid() function The geom_smooth() function

A data analyst is working with the penguins data. The analyst creates a scatterplot with the following code: ggplot(data = penguins) + geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g, alpha = species))What does the alpha aesthetic do to the appearance of the points on the plot? 1 pointMakes the points on the plot larger Makes some points on the plot more transparentMakes the points on the plot smallerMakes the points on the plot more colorful

What is the purpose of using a scatter plot?Review LaterTo show the distribution of a single variableTo compare the distribution of two variablesTo show the relationship between two variablesTo show the ranking of categories
