Q: The data below is how many minutes that I have read each day for 15 days.
Compare the data from the first 10 days to the last 5 days
20, 10, 17, 20, 60, 0, 30, 0, 0, 0, / 15, 15, 30, 25, 18
Is the larger sample changing anything?
Is your mean increasing or decreasing?
Do you think the current sample you have is enough to paint an accurate picture, or do you need a much larger sample?
Now using Excel, prepare a frequency distribution from the following data
20, 10, 17, 20, 60, 0, 30, 0, 0, 0
Calculate the Standard Deviation of your data.
Is this a normal distribution?
What are the implications?
