What is the mean of the data given? 1,1,1,2,2,3,5,6,7,7,8 {Ans: Solution: 1+1+1+2+2+3+5+6+7+7+8= 43 43/11= 3.91}How do you find the mean? {Ans: add up all the numbers and divide by how many numbers there are (sum divided by the count)}What would a graph look like if the data was skewed left? {Ans: More of the data would be to the right of the graph making the bell curve higher to the right and lower to the left.}What would a graph look like if the data was normally distributed? {Ans: It would look like a standard bell curve.}What is the mode of the data given? 1,1,1,2,2,3,5,6,7,7,8 {Ans: 1 is the mode because it appears the most (3 times).}What is the symbol for population mean and sample mean? {Ans: Population mean= μ Sample mean= x̄}What is the range of the data given? 1,1,1,2,2,3,5,6,7,7,8 {Ans: Solution: 8-1=7 The range is 7.}What is mode? {Ans: the value that appears most often in a set of data values}What is median? {Ans: the middle value in a set of data values (or between the middle values if the # of data values is even)}What is the median of
