Data Analysis

Let’s fill in our Concept Map!

Match the graph and definition

First

2nd

***You must choose intervals that separate the data into EQUAL groups. Each interval will be the same size, but might not contain the same frequency of data as every other interval.

Let’s See how we would put one together!

Step 1: Survey students. Record the results.

Number of hours of TV

III 6 II 1

IIII - IIII 7 IIII 2

III 8 IIII - IIII 3

IIII 9 IIII - I 4

IIII - III 5

Step 2Frequency

Table

• Make a frequency table of the data. Be sure to use equal intervals

Number of hours of TVIII 6 II 1IIII - IIII 7 IIII 2III 8 IIII - IIII 3IIII 9 IIII - I 4

IIII - III 5

Frequency Number of hours of TV

15 1-317 4-616 7-9

Step 3Make histogram

Frequency Number of hours of TV

15 1-317 4-616 7-9

• Choose an appropriate scale and interval for the vertical axis. The greatest value on the scale should be at least as great as the greatest frequency.

Step 4• Draw a bar for each

interval. The height of the bar is the frequency for that interval. Bars must touch but not overlap.

• Label the axes and give the graph title

Frequency Number of hours of TV

15 1-317 4-616 7-9

Final Product!
