Before the regional finals, Emek and Tara joined the coaching staff in the stadium strategy room. The scoreboard displayed the team's successful passes from the last six matches: 41, 38, 40, 42, 39, and 40. They calculated the mean to understand the team's average performance and examined how closely the results stayed around that value. The small spread showed that the passing results were consistent. Using this data, the coach selected a strategy based on reliable teamwork, and the team entered the championship with confidence.

Hint
Add all values and divide by the number of matches.
The team's successful passes in the last six matches were 41, 38, 40, 42, 39, and 40. What was the mean number of successful passes?
40394142Correct! The total is 240, and 240 / 6 = 40.
Remember to find the average by adding all values and dividing by 6.
Next🎉 Congrats! You got this question!
Hint
The range is found by subtracting the smallest value from the largest value.
Using the pass results 41, 38, 40, 42, 39, and 40, what is the range of the data?
Correct! The largest value is 42 and the smallest value is 38, so the range is 4.
Check the difference between the highest and lowest pass counts.

Hint
Think about how far the values are from the average.
The coach wants to choose a strategy based on consistency. Which statement best describes the team's passing data?
The results are inconsistent because the values are all different.The results are consistent because the values are close to the mean.The results cannot be compared because there are only six matches.The results are unreliable because the mean is exactly 40.Correct! Most values are close to the mean of 40, showing a small spread and consistent performance.
Consider whether the data values are close to or far from the mean.
