... In a physics laboratory experiment, students drop a ball 50 times and record the time it takes for the ball to fall 2.00 m. One set of observations, corrected for systematic errors, ranges from about 0.59 s to 0.70 s, and some of the observations are identical. Figure 1.2 shows a histogram or ...

... ¾ We repeatedly take random samples and calculate means. Then we use these means as a variable and create a frequency distribution. This distribution represents the mean of every sample that possibly could be selected. It is a sampling distribution. ¾ The distribution of sample means will be normall ...
