Sammi wanted to create a dot plot based on this tally chart.
A 2-column table with 4 rows. Column 1 is labeled Hours with entries 3, 4, 5, 6. Column 2 is labeled Tally with entries 4, 6, 3, 5.
In which step, if any, did Sammi make a mistake creating his dot plot?
Steps to Create a Dot Plot
Step 1
Create a number line.
A number line going from 3 to 6.
Step 2
Title the Dot Plot
A number line titled How Many Hours did you read last week question mark going from 3 to 6.
Step 3
Plot the Points
A dot plot titled How Many Hours did you read last week going from 3 to 6. 3 has 4 dots, 4 has 6 dots, 5 has 3 dots, and 6 has 5 dots.
Sammi made a mistake in Step 1 because his number line did not include all numbers in the data set.
Sammi made a mistake in Step 2 because he chose a title without knowing if the table represents the number of hours read per week.
Sammi made a mistake in Step 3 because he did not correctly plot each dot above the appropriate place on the number line.
Sammi did not make a mistake.
