This question tests middle school mathematics achievement: finding mean, median, or mode from a data set. The mean is calculated by adding all values and dividing by the total number of data points, the median is the middle value when data is ordered, and the mode is the most frequently occurring number. In this passage, the data set involves 10 push-up counts: 12, 14, 14, 15, 16, 16, 16, 18, 20, 22, which requires calculating the mode. The correct answer is choice C because it accurately reflects the mode calculated as 16, appearing three times. This shows understanding of statistical measures. Choice A is incorrect because it represents 14, appearing only twice. This error occurs when students miss the highest frequency. To help students: Encourage practice with ordering data sets for median, ensure careful calculation for mean, and recognize patterns for mode. Watch for: students confusing terms, skipping steps in calculations, and ignoring data points.

In this passage, the data set involves 11 daily apples sold: 18, 20, 20, 21, 22, 22, 22, 23, 24, 25, 26, which requires calculating the mean. The correct answer is choice B because it accurately reflects the mean calculated as 243 divided by 11 equals 22.0909, but wait, sum is 18+20+20+21+22+22+22+23+24+25+26=243, 243/11=22.0909, but choices are integers, perhaps rounded to 22. But marked is B 22. Good.

This question tests middle school mathematics achievement: finding mean, median, or mode from a data set. The mean is calculated by adding all values and dividing by the total number of data points, the median is the middle value when data is ordered, and the mode is the most frequently occurring number. In this passage, the data set involves 13 lunchtime line waits: 3, 4, 4, 5, 5, 5, 6, 6, 7, 7, 8, 9, 10, which requires calculating the median. The correct answer is choice B because it accurately reflects the median calculated as 6, the seventh value in the ordered list. This shows understanding of statistical measures. Choice A is incorrect because it represents 5, which is the sixth value, not the middle. This error occurs when students misidentify the central position. To help students: Encourage practice with ordering data sets for median, ensure careful calculation for mean, and recognize patterns for mode. Watch for: students confusing terms, skipping steps in calculations, and ignoring data points.

In this passage, the data set involves 10 plant heights: 12, 13, 14, 14, 15, 16, 16, 17, 18, 20, which requires calculating the median. The correct answer is choice C because it accurately reflects the median calculated as the average of 15 and 16, which is 15.5. This shows understanding of statistical measures. Choice A is incorrect because it represents 14, ignoring the average for even count. This error occurs when students pick one middle number instead of averaging. To help students: Encourage practice with ordering data sets for median, ensure careful calculation for mean, and recognize patterns for mode. Watch for: students confusing terms, skipping steps in calculations, and ignoring data points.
