A recent study favorably evaluates the con struct validity of the DIAL-3 through confirmatory factor analysis (Assel & Anthony, 2009). As noted the instrument was designed to screen for devel opmental delays in three domains: motor abilities, conceptual knowledge, and language competence. An essential feature of the test is that separate scores are reported for each domain. These domains and the 74 fubtests comprising them were rationally precon- derved by the test authors. An important question is whether the 21 subtests “hang together” statistically in a manner that supports the rational grouping into the three domains provided by the test developers, In other words, do the three domains possess a latent reality, or are they merely figments of the imagina- tions of the test developers? Using test results for 1,560 children ages 3 to 6, Assel and Anthony (2009) found an excellent fit between the three domains tra- ditionally reported on the DIAL-3 and three empiri- cally derived domains found through factor analysis, which supports the construct validity of the test. However, these authors did note that Articulation subtest was a poor index of language compe Cotchine subteet

8. The NBI data were analyzed and the results made available at the FHWA Web site. Using the FHWA inspection ratings, each of the 608,272 highway bridges in the US was categorized as structural deficient, functionally obsolete, or safe. About 13.5% of the bridges were found to be structural deficient, while 3.5% were functionally obsolete. a. What is the variable of interest to the researchers? b. Is the variable of part a quantitative or qualitative? c. Is the data set analyzed a population or a sample? Explain. d. How did the NBI obtain the data for the study?

6.The National Science Foundation (NSF) sponsored a study on girls participation in informal science, technology, engineering, or mathematics (STEM) programs. The results of the study were published in Cascading Influences: Long-Term Impacts of Informal STEM Experiences for Girls (March 2013). The researchers sampled 174 young women who recently participated in a STEM program. They used a pie chart to describe the geographic location (urban, suburban, or rural) of the STEM programs attended. Of the 174 participants, 107 were in urban areas, 57 in suburban areas, and 10 in rural areas. a. Determine the proportion of STEM participants from urban areas. b.Determine the proportion of STEM participants from suburban areas. c.Determine the proportion of STEM participants from rural areas. d. Multiply each proportion in parts a-c by 360 to determine the pie slice size (in degrees) for each location. e.Use the results, part d, to construct a pie chart for geographic location of STEM participants. f.Interpret the pie slice for urban areas. g.Convert the pie chart into a bar graph.
