For the dataset: 20, 20, 10, 10, 40, 50, 20, 30, 10, 20, 50, 60, 20, 30, 50, 20, 30, 40, 30, 30, 30, 50, 40 calculate the max, min, mode, median and mean.(20%)
Draw a boxplot with inner and outer fence
For the data in part (i), if the value 60 was replaced by 2000, what would you call this value in the dataset? What could be the explanation for such a value? How can you through the boxplot decide if this value should be excluded from your analysis
Draw a histogram of the data with four equal sized classes and comment how close to a normal distribution the data look like being
What would be the new values for the three measures of central location with the value of 2000 instead of 60. Comment on the differences
