Objectives of This Activity Create a Histogram Graph of a Given Variable Using SPSS Displaying the Normal Curve on the Histogram Using SPSS Assessing Normality of a Variable Distribution Using Q-Q Plot Use Normality Tests. Standardizing a Variable Using SPSS. 1. Open the data set babyBoomData.sav. 2. Assess the normality of the weights of babies using all three methods (histogram with normal curve, a Q-Q Plot, and Normality Tests). Does the newborn weight appear to be normally distributed? Explain. 3. Find the mean and standard deviation of the weights of newborns. 4. Standardize the weights of the newborns. How many babies are further than 1-standard deviation from the mean weight? If any exists, nd their weight and determine how many deviations from the mean they are. Please attach all SPSS output to this sheet. Dr. Emmert Summer 2011 I of I Points Earned...
