a. Distinguish between description and inference as reasons for using statistics. b. Suppose you have data for a population, such as obtained in a census. Explain why descriptive statistics are helpful, but inferential statistics are not needed. a. Which statement below best distinguishes description from inference? A. Statistical inference provides useful summaries of the data, while description helps make predictions and decide whether observed patterns are meaningful. B. Statistical inference provides useful summaries of data for a sample, while description...

You have been asked by a men's clothing manufacturer, Nuke, to provide advice on whether there is evidence of differences in the average heights of male citizens in three different countries. You have taken random samples of the heights of males (in cms) in those three countries and your data set is attached in csv delimited format (as a .txt file) using the link on the right. Input the data set into SPSS and perform the appropriate analysis to answer...

7.3.5 In a study of parents' perceptions of their children's size, researchers Kaufman et al. (Current Biology, 2013) asked parents to estimate their youngest child's height. The researchers hypothesized that parents tend to underestimate their youngest child's size because the youngest child is the baby of the family and everybody else is the family appears bigger compared to the baby The researchers also surveyed a sample of 35 parents about their eldest child's height. The parents overestimated their eldest child's...

Children's height as a function of their age has been researched so extensively that we can consider known results to describe the relationship for all children in the United States. For instance, between the ages of 13 and 15, population mean height for teenage males (in inches) satisfies μy = 22 + 3x, where x is age in years. Spread about the line is 3.1 inches. (a) Notice that the slope of the regression line for the population is β1...
