The four variables are used to analyze the motion picture industry‚ and show the descriptive statistic of the variables and to analyze the results. The results will show the high performance outliers of the motion picture industry and why. The correlation between total gross sales and each variable will be shown and will be accompanied by X‚ Y scatter graphs.

Error Analysis Lab By: Lab Team 5 Introduction and Background: In the process of learning about the importance of measurement and data processing‚ lab teams were given prompts to design experiments as well as address the precision‚ accuracy‚ and error analysis within the experiment. Lab teams collaborated their data to find similarities and differences within their measurements. Through this process‚ students learned the importance of the amount of uncertainty as well as the different

and the maximum value is much farther away from the median than the minimum value. (b) Would the boxplot for the data indicate any outliers? Explain why or why not. Ans: IQR=9100-8850=250. 1.5 × IQR = 375. The inner fences will be 8850-375=8475 and 9100+375=9475 respectively. With a maximum of 9940‚ there is at least one high outlier. (There will be no low outliers because the minimum is 8800‚ which is within the inner fences.) II. A drug manufacturer has hundreds of sales representatives all

Chapter 1 Multivariate analysis refers to all statistical techniques that simultaneously analyze multiple measurements on individuals or objects under investigation. Factor analysis identifies the structure underlying a set of variables Discriminant analysis differentiates among groups based on a set of variables. All the variables must be random and interrelated in such ways that their different effects cannot meaningfully be interpreted separately. Nonmetric measurement scales Nominal
