STATISTICAL ANALYSIS FOR MEDICAL RESEARCH Using SPSS
Day 1
Determining Sample Size
Mr. Ahmad Alsaber
Example 1: Comparing two means
A placebo-controlled randomized trial proposes to assess the effectiveness of Drug A in preventing the stress response to laryngoscopy. A previous study showed that there is the average rise of 20 mm of Hg in systolic blood pressure during laryngoscopy (with SD of 15 mm of Hg). What should be the sample size to study the difference in mean systolic blood pressure between two groups with a significant P < 0.05 and power of study of 90%.
Descriptive Statistics
Mr. Ahmad Alsaber
(1) Formatting tables using APA
(2) show the descriptive statistics for the demographics
(3) show the descriptive statistics for the study variables
(4) show the normality analysis for each factor.
Comparing between groups
Mr. Ahmad Alsaber
(1) Two independent groups
(2) More than two independent group
(3) Paired or repeated trails
(4) Chi-Square test
Research #1
Mr. Ahmad Alsaber
Logistic regression is used to predict a categorical (usually dichotomous) variable from a set of predictor variables.
As an example of the use of logistic regression in psychological research, consider the research done by Wuensch and Poteat and published in the Journal of Social Behavior and Personality, 1998, 13, 139-150.

and how to use it in the discussion
Journals Metric
SCImago Journal Rank is a measure of scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from.
Alternative to SPSS
JASP is a free and open-source graphical program for statistical analysis supported by the University of Amsterdam. It is designed to be easy to use, and familiar to users of SPSS.
Research Networking
ResearchGate is a European commercial social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators.
