Read the scenario below to determine which one of the time threats to internal validity (test reactivity, instrumentation, history and maturation) is of most concern and provide one way of controlling for the threat. In a short experiment designed to investigate the effect of computer-based instruction, students missed some instruction because of a power failure at the school

Read the scenario below to determine which one of the time threats to internal validity (test reactivity, instrumentation, history, and maturation) is of most concern, and provide one way to control for the threat. A researcher examines students’ perception of their body image by conducting a 2-year longitudinal study of middle-school students (grades 6 – 8). Body image is measured using a scale and the same scale is measured under the same conditions at the beginning and end of the study.

Read the scenario below to determine which one of the five areas of construct validity (content, response processes, internal consistency, relationship to other variables and consequences) is of most concern. Researchers developing a new and different exam for admission into graduate school begin by constructing a table of specifications for the exam.

19. Suppose the nitrogenous base sequence below is a short mRNA molecule. mRNA processing has already taken place. Use the mRNA codon table provided to simulate translation (as performed by a ribosome) by determining the amino acid sequence specified by this mRNA strand. Write the correct amino acid sequence in the space provided. You may use amino acid abbreviations. 5ʹ A G G C G C U U G A U G C G U G U U A C U A U U G G C U G A A A U A A A A U A A A 3ʹ

13. Below are several representations of messenger RNA. Rather than type out nitrogenous base sequences, I am representing sequences with the words Intron and Exon to indicate whether that particular segment of mRNA is an intron or an exon. Untranslated regions of mRNA are not shown. Which representation shows an mRNA molecule after processing (all steps of mRNA processing have taken place).
