Chapter 2 Charts and Graphs Statistics is the science of data. A first step in the study of statistics is the examination of data. Chapters 2 and 3 present several techniques for reducing data so that it is more manageable. In addition‚ graphic displays are essential to understand and interpret complex sets of data in order to be able to make business decisions easier. Chapter 2 discusses and displays several graphical tools including the histogram‚ frequency polygon‚ ogive‚ dot plot‚ bar

9.18 a) Using forward stepwise regression to find the best subset of predictor variables to predict job proficiency. The Alpha-to-Enter significance level was set at 0.05 and the Alpha-to-Leave significance level was set at 0.10. The first predictor entered into the stepwise model is X3. SAS tells us that the estimated intercept is -106.13 and the estimated slope for X3 is 1.968. The R2-value is 0.8047‚ mean square error is 76.87. The second predictor entered into the stepwise model is X1.

Statistics is the study of the collection‚ organization‚ analysis‚ interpretation‚ and presentation of data.[1][2] It deals with all aspects of this‚ including the planning of data collection in terms of the design of surveys and experiments. In mathematics‚ a graph is a representation of a set of objects where some pairs of the objects are connected by links. The interconnected objects are represented by mathematical abstractions called vertices‚ and the links that connect some pairs of vertices

that would answer particular questions on a Likert scale of ten points‚ we would be able to measure and therefore treat the variables as interval variable so that we can statistically analyze our data. According to (Miles‚ 2010 pp. 8)‚ asking for a subjective evaluation of a particular element may render the measurement as ordinal rather than interval‚ we would address this challenge by creating defined criteria’s where we can evaluate the answers given against guidelines and reject answers that would
