SPSS statistics homework

Data collection, data recording, and demographic/descriptive information are presented first followed by the results that directly relate to the hypotheses.

Data Collection Comment by james wolosin: This goes in Methods, not Results

Data collection occurred at the beginning and the end of the study, and each participant was assigned a number to ensure confidentiality. I obtained data from one source divided in two different parts: (1) an 11 item survey that contained the time it took to complete Fran, demographic information (gender, age, weight, and height coded numerically), exercise habits (by number of days per week), eating habits divided in four categories (fast food, fried food, flour, and sugar intake by number of days per week), and pre and post workout supplements (coded numerically). (2) the second part of the survey consisted of three items containing cheat meals during the study (by numbers of days), missed training days (by number of days), and the time it took to complete Fran a the end of the study.

Data Recording Process

The data collected were transferred into a statistical database (SPSS). The independent variable (Paleo diet with rice), the dependent variables (time it takes to complete Fran), demographic information, exercise and eating habits, as well pre and post workout supplements (coded numerically) were recorded. Three survey items were recorded at the end of the study; cheat meals, miss training days, and the time it took to complete Fran at the end of the study. There was no missing data during the recording process. The numerical identifiers for each participant were entered into the database and participants names were kept in a separate location.

Reliability, Validity, and Bias

Internal-consistency reliability was performed on the eating habits of the participants (fast food, fried food, four, and sugar) using a Cronbach Alpha. All measures met acceptable standards of reliability (r > .68). Content validity of the evaluation ratings and performance measures was established by agreement among subject matter experts (full-time department members who have taught these classes). In addition, construct validity of the pre and post test (Fran WOD) was checked by correlating these measures with food intake for the pre test (all categories in within range) and missed training days (r> .047 positive correlation), and cheat meals (r> .26 positive correlation) for the post test. Validity show to be in within range for Pearson correlation in all categories. Finally, subject matter experts reviewed each item to assess possible bias, but no suspicious items were found and none was removed. Comment by james wolosin: This is not correct. These are ordinal variables. You can’t perform an Internal Reliability analysis Comment by james wolosin: This is not how you report CA. Comment by james wolosin: None of this makes any sense.

Demographic and Descriptive Results

Fifty percent of the participants were female. All of the participants were at an average athletic level. As an average there was an improvement in the time it took to complete Fran from the pre-test to the post-test.

Testing Hypothesis (state hypothesis)

The hypothesis was test used a t-test for independent samples, t(19) = 2.50, p≤.05. When observing the measures in between the pre and post-test, I expected the time to complete Fran towill significantly decrease on the post-test after the participants followed the Paleo with rice. In the end, when tThe data was plotted into a graph, the study showed that the time to complete Fran improved during the post-test. The results were 8.44 minutes/seconds compared to 9.71 minutes/seconds respectively. Using a t-tests, the results showed a significant difference in between pre-test and the post-test. The t-test returned Only in the second stage of hiring, the time it took from the hiring test to the oral interview was there a significant difference in terms of time. The t-test for the second stage returned t(19)=2.50, p≤.05 as a result, meaning I could rule out the null hypothesis. Comment by james wolosin: Where is reference to the graph in the appendices? Comment by james wolosin: Significantly? Comment by james wolosin: Is this an average for the Pre-Test? Comment by james wolosin: Post-test? Comment by james wolosin: What is this? This has nothing to do with any hypothesis

Exploratory Analysis (?)

Utilizing a univariate analysis where a single independent variable was tested show that the results were not influenced by either the gender or age. Comment by james wolosin: One-Way ANOVA? Where are the results? Where is reference to the ANOVA table?
