The test rejects the hypothesis of normality when the p-value is less than or equal to 0.05. Failing the normality test allows you to state with 95% confidence the data does not fit the normal distribution. Passing the normality test only allows you to state no significant departure from normality was found.

Nov 23, 2018 · How to Shapiro Wilk Normality Test Using SPSS Interpretation | The basic principle that we must understand is that the normality test is useful to find out whether a research data is normally distributed or not normal. In parametric statistical analysis the requirements that must be met are data that are normally distributed. SPSS Tutorials: Paired Samples t Test - Kent State University Note: When testing assumptions related to normality and outliers, you must use a variable that represents the difference between the paired values - not the original variables themselves. Note: When one or more of the assumptions for the Paired Samples t Test are not met, you may want to run the nonparametric Wilcoxon Signed-Ranks Test instead. Statistical notes for clinical researchers: assessing ... Feb 26, 2013 · The formal normality tests including Shapiro-Wilk test and Kolmogorov-Smirnov test may be used from small to medium sized samples (e.g., n < 300), but may be unreliable for large samples. Moreover we may be confused because 'eyeball test' and 'formal normality test' may show incompatible results for the same data. Normality Tests for Statistical Analysis: A Guide for Non ...
SPSS: Realize that a paired-samples t-test corresponds to a one-sample t-test of the pairwise differences. Then compute that difference using Data → Compute variable… → diff = var2 – var1 . Then head to Analyze → Descriptives → Explore → Plots → Normality plots with test and run the analysis on the newly computed “diff” column.

Testing for Normality using SPSS Statistics Introduction. An assessment of the normality of data is a prerequisite for many statistical tests because normal data is an underlying assumption in parametric testing. There are two main methods of assessing normality: graphically and numerically.
Bivariate (Pearson) Correlation in SPSS. At this point it would be beneficial to create a scatter plot to visualize the relationship between our two test scores in reading and writing. The purpose of the scatter plot is to verify that the variables have a linear relationship. Descriptive statistics | SPSS Annotated Output This page shows examples of how to obtain descriptive statistics, with footnotes explaining the output. The data used in these examples were collected on 200 high schools students and are scores on various tests, including science, math, reading and social studies (socst).The variable female is a dichotomous variable coded 1 if the student was female and 0 if male.
