Standard deviation sig figs - Mathematics Stack Exchange When reporting the results of a repeated measures ANOVA, we always use the following general structure: A brief description of the independent and dependent variable. The APA doesn't have a specific rule about Cronbach's alpha, but they recommend reporting correlations to two digits (e.g. It is not easy to see that JS2 has the highest number. (xi - x)2. ° Report exact p values to two or three decimals (e.g., p = .006, p = .03). If you measured time in milliseconds (ms) the mean and standard deviation might be reported as M= 1250 ms, SD= 235 ms. (Round your standard deviation to 2 decimal places.) A zero should be used in front of the decimal place for numbers that are less than 1, but the value could exceed 1 (e.g., Cohen's d = 0.50). Use the tables feature of your word-processing program to create tables in APA Style papers. They can only correlate between -1.0 and 1.0; at either of these points the two are perfectly correlated, so a single-unit change in one variable results .

Fewer decimal digits are easier to understand - round off to two decimal places or rescale the measurement 1.6784 m can be rescaled to 167.85cm Reporting data measured on integer scales (e.g., questionnaires), report means and standard deviations to one decimal place M = 5.2 SD = 1.5 Report correlations, proportions and Using more indicates that you data is more precise than it is. If your data is rounded to one decimal, each item is uncertain by ± 0.05. PDF Statistical Analysis in JASP - A Student Guide v1.0 The centre of a distribution can be described by its mean or median, and the spread by its standard deviation (SD), range, or inter-quartile range (IQR).
