For the following questions, refer to this table, named planet-data.
Question 1
How would you use the plotting library to make this scatter plot?
( ) plot(planet-data, "distance_from_sun", "orbital_speed")
( ) scatter-plot(planet-data, "orbital_speed", "distance_from_sun")
( ) scatter-plot(planet-data, "distance_from_sun", "orbital_speed")
( ) plot(planet-data, "orbital_speed, "distance_from_sun")
Answer
scatter-plot(planet-data, "distance_from_sun", "orbital_speed")
The scatter-plot function takes in the name of the table, the string column name for the x-axis, and the string column name for the y-axis.
Question 2
Fill in the blanks to create this pie chart:
pie-chart(planet-data, [arg1], [arg2])
Arg1: ______
Arg2: ______
Answer
Arg1: "planet"
Arg2: "mass"
The pie-chart function takes in the name of the table, the string column name for the labels, and the string column name for the values in the pie chart.
Question 3
Which of these answer choices correctly displays a histogram that shows the distribution of the planets' mass with a bin-width of 50?
( ) histogram(planet-data, 50, "mass")
( ) histogram(planet-data, "planet", "mass")
( ) histogram(planet-data, "mass", "planet")
( ) histogram(planet-data, "mass", 50)
Answer
histogram(planet-data, "mass", 50)
The histogram function takes in the name of the table, the string column name for the value to analyze, and a number for the bin-width of the histogram.
Question 4
True or False– The functions in the plotting library all output data of type Plot.
( ) True
( ) False
Answer
False
The plotting functions all output data of type Image.
Question 5
Write the function call to produce this graph.
Answer
bar-chart(planet-data, "planet", "radius")
The bar-chart function takes in the name of the table, the string column name for the x-axis, and the string column name for the y-axis.
Question 6
Write the function call to produce this graph.
Answer
box-plot(planet-data, "radius")
The box-plot function takes in the name of the table and the string column name of the value to analyze.
