PSPP. Features This software provides a comprehensive set of capabilities including frequencies, cross-tabs comparison of means (t-tests and one-way ANOVA); linear regression, logistic regression, reliability (Cronbach's alpha, not failure or Weibull), and re-ordering data, non-parametric tests, factor analysis, cluster analysis, principal components analysis, chi-square analysis and more.

Some very advanced statistical tests are as of 2014 not yet implemented. At the user's choice, statistical output and graphics are available in ASCII, PDF, PostScript, SVG or HTML formats. A range of statistical graphs can be produced, such as histograms, pie-charts scree plots and np-charts. PSPP can import Gnumeric and OpenDocument spreadsheets, Postgres databases, comma-separated values and ASCII files. Origins Release history PSPP 0.8.3 running on Windows 7.

Here is a tick off what you need to know sheet for correlations. Don't let yourself fall into the trap of believing that when there is a strong correlation between two variables that one of the variables causes the other. Association does not mean causation. Correlation (Pearson, Kendall, Spearman) - Statistics Solutions. Correlation is a bivariate analysis that measures the strengths of association between two variables.

In statistics, the value of the correlation coefficient varies between +1 and -1. When the value of the correlation coefficient lies around ± 1, then it is said to be a perfect degree of association between the two variables. As the correlation coefficient value goes towards 0, the relationship between the two variables will be weaker. Encyclopedia of Psychology. Correlation Method in Psychology. By Saul McLeod published 2008 Correlation means association - more precisely it is a measure of the extent to which two variables are related.

If an increase in one variable tends to be associated with an increase in the other then this is known as a positive correlation. An example would be height and weight.

This simple question is a never-ending quandary for researchers. A larger sample can yield more accurate results — but excessive responses can be pricey. Consequential research requires an understanding of the statistics that drive sample size decisions. A simple equation will help you put the migraine pills away and sample confidently. #YouHadToBeThere: On Social Media & Self-Esteem.
