Question

the stacked line chart shows the numbers of college degrees awarded to males and females since 1970. complete parts (a) through (d).
a. estimate the numbers of college degrees awarded to males and to females (separately) in 2020.
the number of college degrees awarded to males in 2020 was dropdown. the number of college degrees awarded to females in 2020 was dropdown.
options:
693,000
770,000
616,000
1,193,000

Explanation:

Read the male value in 2020

Using the Stacked Line Chart Interpretation and Stacked Chart Reading knowledge points

• Locate the year 2020 on the horizontal axis.
• The bottom region (cyan) represents the number of degrees awarded to males.
• The top of the cyan region in 2020 aligns exactly with the grid line at 8.
• Since the vertical axis is in "hundred thousands", \(8 \times 100,000 = 800,000\).
• Looking at the dropdown options, \(770,000\) is the closest estimate to 800,000.

Read the total value in 2020

Using the Stacked Line Chart Interpretation and Stacked Chart Reading knowledge points

• The top boundary of the stacked chart (purple region) represents the total degrees awarded (males + females).
• In 2020, the top of the purple region aligns exactly with the grid line at 20.
• This corresponds to \(20 \times 100,000 = 2,000,000\) total degrees.

Calculate the female value in 2020

Using the Stacked Line Chart Interpretation and Stacked Chart Reading knowledge points

• Subtract the male value from the total value to find the female value:

$$ \text{Female Degrees} = \text{Total Degrees} - \text{Male Degrees} $$

• Using our estimates:

$$ 2,000,000 - 770,000 = 1,230,000 $$

• Looking at the dropdown options, \(1,193,000\) is the closest estimate to 1,230,000.
