Below are sample questions representative of the exercises included on this worksheet and related 8.06 Data Tables, Graphs and Best Fit Lines skill assessments:

Problem 1Difficulty: Mastery

A student wants to investigate how ramp height affects how far a toy car travels. Which option is the best overall plan?

AUse a table with only the farthest distance and make a circle graph of the ramp heights.

BWrite the distances in a paragraph and draw a bar graph with no axis labels.

CUse a table with Ramp height (cm), Trial 1 distance (cm), Trial 2 distance (cm), Trial 3 distance (cm), and Average distance (cm); then make a scatter plot with a best-fit line and note any outlier to recheck.

DUse a table without units and connect the points in random order.

Solution & Explanation:The best plan organizes repeated trials clearly, includes units and averages, uses a graph suited to two numerical variables, and handles outliers carefully.

Problem 2Difficulty: Mastery

A student used a bar graph to show water temperature every minute during heating and then tried to describe how fast the water warmed at different times. What is the best revision?

AUse a line graph so changes over time and differences in slope are easier to interpret.

BKeep the bar graph because any graph can show rate equally well.

CUse a pie chart because the temperatures add up to a whole.

DDelete the time labels so the pattern is clearer.

Solution & Explanation:A line graph is better for continuous change over time and makes it easier to compare rates by looking at slope.

Problem 3Difficulty: Mastery

Two groups test different liquids and each group records three trials at every temperature. If the goal is to compare the liquids fairly on one graph, what should be plotted?

AOnly the single highest trial from each temperature

BThe average value for each liquid at each temperature, while keeping raw trials in the table

CNo graph at all because repeated trials are too complicated

DA circle graph of the number of trials completed

Solution & Explanation:Averages help compare the liquids fairly across temperatures, while the raw trial data should still be preserved in the table.
