Data Analysis Worksheet

Space mission data challenge: use the datasets and visual displays on this page. Show working for calculations and explain what the statistics tell you.

Mission 1: Crew Training Scores

Mei recorded eight crew members’ training scores (out of 100): 56, 62, 75, 75, 80, 85, 92, 100.

1.Find the mean training score. Show your calculation.
2.Find the median, mode and range of the training scores.
3.Omar says the mean is the score that appears most often. Is he correct? Name the statistic he is describing and explain briefly.

Mission 2: Supply Pack Weights

Dylan checks the mass, in kilograms, of eight supply packs: 5, 7, 8, 9, 10, 11, 12, 50. Use the number line to help inspect the spread.

4.Place the eight pack masses on the number line. Which value is separated most from the rest?
05101520253035404550
5.Find Q1 and Q3 using the median-of-halves method, then calculate the IQR.
6.Use lower fence = Q1 − 1.5 × IQR and upper fence = Q3 + 1.5 × IQR. Calculate both fences and identify any outlier.

Mission 3: Comparing Two Flight Simulators

Two simulator groups completed the same training task. Group A scores: 50, 55, 60, 65, 70, 75. Group B scores: 50, 55, 60, 65, 70, 200. Treat the values as recorded for this statistics exercise.

7.Calculate the mean and median for each group.
8.Calculate the range for each group. Which group has greater spread by range, and why?
9.Which measure—mean or median—better represents a typical score in Group B? Explain how the extreme score affects the other measure.
10.A new Group B score of 65 is added. Without calculating every statistic, predict whether the median changes and explain your reasoning.
