After considering Mary's study into whether the learning of 6th graders on a math lesson is affected by background noise levels. Mary option of utilizing a repeated measures design for this study, as a repeated-measures study allows for the management of the sample size of the overall study which is one of the major benefits of the repeated-measures study, issues arise in the repeated-measures study due to the use of identical participants found in the group instead of conducting the study with differing samples to increase the variety of the sampling of students participating in the study (Gravetter & Wallnau, 2013). For the study the use of SPSS will allow Mary to select an ANOVA as a form of analysis for the effect of background noise levels on the 6th grade students when given a math lesson. Additionally, ANOVA does not require tabulated data sets as an input or for the data to be sorted for the completion of the analysis, particularly with the ONEWAY ANOVA analysis providing for seven different test statistics for posteriori analysis and the ability to run priori as a subprogram of the ONEWAY ANOVA analysis, and ANOVA permits Mary to acquire analyses of variance for factorial designs, tolerating up to five factors in each design.
