We perform tests appropriate for the purpose of clinical research with SPSS software.
Normality tests (Parametric and non-parametric)
Parametric Tests: Checks whether the data is normally distributed. For example, Kolmogorov-Smirnov and Shapiro-Wilk tests.
Non-Parametric Tests: Used when the data is not normally distributed. For example, Mann-Whitney U test, Kruskal-Wallis test.
Descriptive Statistics
It summarizes the basic characteristics of the data. It includes measurements such as mean, median, mode, standard deviation, and variance.
Repeated Statistics
Analyzes data collected from the same individuals over time or under different conditions, for example, repeated measures ANOVA (RM-ANOVA).
Comparative Statistics
Used to determine differences between two or more groups. Tests such as t-tests and ANOVA fall into this category.
Survival Statistics
Analyzes the time it takes for a specific event (e.g., death, illness) to occur. Kaplan-Meier analysis and Cox regression are among these methods.
Regression Statistics
It is used to examine the relationship between a dependent variable and one or more independent variables. There are types such as linear regression and logistic regression.
Analysis of variance (ANOVA)
It is used to compare means between multiple groups. There are types such as one-way ANOVA and two-way ANOVA.
Factor Analysis, Roc Analysis, Correlation Analysis etc.
Factor Analysis: Examines the relationships between many variables and allows these variables to be grouped under fewer factors.
Roc Analysis: Used to measure the accuracy of a test. The ROC curve compares sensitivity and specificity rates.
Correlation Analysis: Determines the strength and direction of the relationship between two or more variables. There are types such as Pearson correlation and Spearman correlation.
Roc Analysis: Used to measure the accuracy of a test. The ROC curve compares sensitivity and specificity rates.
Correlation Analysis: Determines the strength and direction of the relationship between two or more variables. There are types such as Pearson correlation and Spearman correlation.
Individual Data Listing (Listing Table)
These are tables that list the data of each individual in detail.
Transfer of Analysis Data
The process of converting and transferring analysis results to other software or formats.
Archiving
Storing analysis results and data in appropriate formats for long-term storage.
