Module 3 Article Discussion 23 Part I Read the article: Trindade, J., Fiolhais, C., & Almeida, L. (2002). Science learning in virtual environments: A descriptive study. British Journal of Educational Technology, 33(4), 471-488. Post responses to the questions below to the group as directed no later than 11:59 pm on January 30th. a) What are the independent and dependent variables and what is the measurement scale of each? b) Name three types of descriptive statistics that were reported in the manuscript? c) Review the boxplots in Figure 3. The legend to the right of the figure indicates that the whiskers represent the standard deviation, the box represents the standard error, and the line represents the median. Have the authors represented the elements of the boxplot correctly? If not, what is incorrect? d) What is the general distributional shape (in terms of normality, skewness, kurtosis) of the histograms represented in Figure 6? e) Based on the results in Table 3, which comprehension score reflected the most variability? What are some reasons why variability differs between the different comprehension scores? Is a large standard deviation reason to cause concern to the author? Why or why not
