A group of students measured the growth of bacteria colonies (in mm): 4,6,5,5, and 30. Which statement best describes the data?, The mean is 10 mm because one unusually high value affects the average., The median is 10 mm because the numbers are spread evenly., The range is 6 mm because 6 − 0 = 6., The range is 6 mm because 6 − 0 = 6.The mode is 30 mm because it is the largest number., Water samples from 8 locations showed the following pH levels: 6.2, 7.0, 6.8, 6.5, 7.4, 6.9, 6.6, 7.1. What is the median pH level?, 6.8, 6.85, 6.9, 7.0, Two groups tested how long (in minutes) it took ice to melt. Group A: 12, 15, 18, 20 and Group B: 14, 15, 16, 17. Which statement is supported by the data?, Group A shows less variation because its highest value is 20., Group B shows less variation because its range is smaller., Group A shows more variation because its median is higher., Both groups show the same variation because they each have four data points., A researcher recorded how many hours of sunlight a plant received over 9 days: 6, 7, 8, 6, 9, 6, 7, 8, 6. Which statement is correct?, The mean is 7 hours., The mode is 7 hours., The median is 6 hours., The mode is 6 hours., Daily high temperatures (°F) over 5 days were: 70, 75, 68, 72, 85. What are the mean and range?, Mean = 74°F; Range = 17°F, Mean = 72°F; Range = 15°F, Mean = 74°F; Range = 15°F, Mean = 75°F; Range = 17°F.
