Tuesday, March 25, 2014

2. Gretta recorded the daily high temperatures for the last 2 weeks.52 56 62 65 60 53 54 58 63 85
Create a dot plot to represent Gretta’s data.
Identify the mean, median, mode, range, and any outlier(s). Describe any patterns or deviations in the data.
How would the removal of a 52 and the 85 affect the range and measure of center (mean, median, mode)? Which measure of center should Gretta use to report the average daily temperature? Explain.
On how many days did Gretta record the temperature?
On how many days was the temperature above 60˚?
