The question was investigated of whether pleasant aromas help a student learn better. All 21 participants learned both under a condition of smelling nothing and under a condition of smelling a floral scent. Counterbalancing was followed so that some participants learned without the scent first and some learned with the scent first. All participants were apprised that the scents were “safe” and that if they wished they could leave the study at any time. Data in terms of “time (in seconds) to complete a pencil and paper maze” are shown below Unscented-Trial Scented-Trial 38.4 53.1 46.2 54.7 72.5 74.2 38.0 49.6 82.8 53.6 33.9 51.3 50.4 44.1 35.0 34.0 32.8 34.5 60.1 59.1 75.1 67.3 57.6 75.5 55.5 41.1 49.5 52.2 40.9 28.3 44.3 74.9 93.8 77.5 47.9 50.9 75.2 70.1 46.2 60.3 56.3 59.9 Indicate the sample size (n = ?), and describe what consequence(s) this sample size will have in terms of analyses and reporting.
