An analyst is reviewing the following data: Car ID Speed 123155 566436 564418 650567 546436 645638 Which of the following should the analyst include in the measures of central tendency for speed?

The correct answer is D. Mode = 36 Median = 37 Mean = 41.5. Measures of central tendency describe the center of a data distribution and include three specific metrics: mean (arithmetic average), median (middle value when sorted), and mode (most frequently occurring value). Option D correctly includes all three - Mode = 36, Median = 37…

Options

AMode = 38 Range = 31 Mean = 42.5
BRange = 49 Max = 67 Min = 18
CMode = 36 Max = 67 Min = 18

Explanation

Measures of central tendency describe the center of a data distribution and include three specific metrics: mean (arithmetic average), median (middle value when sorted), and mode (most frequently occurring value). Option D correctly includes all three - Mode = 36, Median = 37, and Mean = 41.5 - making it the only valid answer. Options A and C include Range and Max/Min respectively, which are measures of dispersion/spread, not central tendency. Option B includes only Range, Max, and Min - none of which are measures of central tendency. The key distinction is that central tendency describes 'where the data is centered,' while spread describes 'how far apart the values are.'
