D.34 Answers: Writing research
Answers to exercises in Sect. 37.17.
Answer to Exercise 37.1: The graph: odd colour choice; vertical axis label isn’t helpful; horizontal axis isn’t labelled at all; units of measurement not given.; title and/or caption would be helpful.The table: the two limits of the CI are under the Mean and Std dev columns, but that is not what they are; units of measurement are not given; no caption, or any way to know what the table is about; number of decimal places is inconsistent. sample sizes not given; difference, and probably the other rows too, should report a standard error.
Answer to Exercise 37.2: RQ: P, O, C and I are not clear or explicit; the two fonts being compared should be identified. Perhaps better: ‘For USC students, is the mean reading speed for text in the Georgia font the same as for text in Calibri font?’
Abstract: statement poorly constructed (fonts are not fast or slow!). Perhaps: ’The sample provided evidence that the mean reading speeds were different (\(P=???\)), when comparing text in Georgia font (mean: ???) and Calibri font (mean: ???; 95% CI for the difference: ??? to ???).
