Examine the data sets. They display the scores for two basketball teams.
Team A: {48,39,47,48,38,30,35}
Team B: {46,39,42,44,38,47,35}
Click on the link to use the GeoGebra graphing calculator to calculate the standard deviation of the data set.
Round your answer to the nearest tenth, if necessary.
Compare the means, ranges, and standard deviations of the data sets. Then use the drop-down arrows to complete the sentences.
The mean score for Team A is [the same as, less than, greater than] the mean score for Team B. Therefore, [the scores for Team B are higher, on average, the scores for Team A and Team B are the same, on average, the scores for Team A are higher, on average].
The range of scores for Team A is [greater than, the same as, less than] the range of scores for Team B. Therefore, [there is a greater difference between the highest and lowest score for Team B than Team A, there is a greater difference between the highest and lowest score for Team A than Team B, there is the same difference between the highest and lowest score for Team A and Team B].
The standard deviation for the scores for Team A is [greater than, less than, the same as] the standard deviation for the scores for Team B. Therefore, [the scores for Team B are more spread out from the mean than the scores for Team A, the scores for Team A are more spread out from the mean than the scores for Team B, the scores for Team A are spread out the same from the mean as the scores for Team B].
