Question

bar & line graph practice (10 points)
directions: create a bar graph using the data table below. be sure to do the following:

• label the x and y-axes using the headings on the data tables
• scientifically title the bar graph
• choose a constant interval for the y-axis
• color each bar a different color and label each bar with the number of students above it

number of students in period 4 | grades
9 | a
7 | b
4 | c
2 | d
1 | f

title: amount of students in pd 4
grid with y - axis labeled 1,2,3,...10 and x - axis labeled a,b,c,d,f, with handwritten numbers and title

Explanation:

Step1: Set up the graph structure

• X - axis: Label the categories as the grades (A, B, C, D, F) since the data table has grades in one column.
• Y - axis: The data for the number of students ranges from 1 to 9. A good constant interval for the y - axis would be 1 (since the values are relatively small and we can clearly represent each value). So we mark the y - axis with intervals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 (to have a bit of extra space at the top).
• Title: A scientific title would be "Number of Students in Period 4 by Grade" as it clearly states what the graph is about (the number of students in period 4 grouped by their grades).

Step2: Draw the bars

• For grade A: The number of students is 9. So we draw a bar above "A" on the x - axis that reaches up to the value 9 on the y - axis. Then label the number 9 above the bar. We can choose a color, say blue, for this bar.
• For grade B: The number of students is 7. Draw a bar above "B" that reaches up to 7 on the y - axis. Label 7 above the bar. Choose a different color, like green.
• For grade C: The number of students is 4. Draw a bar above "C" that reaches up to 4 on the y - axis. Label 4 above the bar. Choose a color, e.g., red.
• For grade D: The number of students is 2. Draw a bar above "D" that reaches up to 2 on the y - axis. Label 2 above the bar. Choose a color, like yellow.
• For grade F: The number of students is 1. Draw a bar above "F" that reaches up to 1 on the y - axis. Label 1 above the bar. Choose a color, e.g., purple.

Answer:

The bar graph is constructed as follows:

• Title: "Number of Students in Period 4 by Grade"
• X - axis: Labels are "A", "B", "C", "D", "F" (representing grades)
• Y - axis: Intervals from 0 to 10 with an interval of 1.
• Bars:
• Bar for A (blue) reaches y = 9, labeled 9.
• Bar for B (green) reaches y = 7, labeled 7.
• Bar for C (red) reaches y = 4, labeled 4.
• Bar for D (yellow) reaches y = 2, labeled 2.
• Bar for F (purple) reaches y = 1, labeled 1.
