What is the square root of pi squared? For what type of population distributions would you recommend using the Wilcoxon Rank Sum Test? How can one conduct a successful experiment? What is sampling theory? What does a Pearson Correlation of -.09 mean?
Statistics: How can I get an R-squared value when a Stata command does not supply one? (Updated 26 June 2017) Statistics: Why do I see different p-values, etc., when I change the base level for a factor in my regression? (Updated 26 June 2017) Windows: Why do I get slightly ...
We successfully validated a revision of the CATI. A confirmatory factor analysis supported the six-subscale structure (two-factor bifactors model: Chi-squared = 2705.73,p< .001, RMSEA = .04, SRMR = .03, CFI = .95, TLI = .94). Spearman’s rank correlations showed positive relationships ...
Common metrics for evaluating a model's performance include accuracy (for classification problems), precision and recall (for binary classification problems), and mean squared error (for regression problems). We cover this evaluation process in more detail in our Responsible AI webinar. Step 6: Hype...
Penalised spline regression is a popular new approach to smoothing, but its theoretical properties are not yet well understood. In this paper, mean squared

Range – 1 – description of dispersion of data used more in everyday life than in scientific statistics - Variance – 1 – description of dispersion of data forms the basis of many statistical tests; in squared units, so not very understandable - Standard deviation – 1 – description of di...
