The mean will say what the average data values are, the median is the middlemost value by quantity, and the mode is the value that occurs the most. Chance: Two groups will often not have the same mean just by chance. The value that we calculate to assess whether the difference is likely due to chance is called the p-value, which is the chance of the observed group difference (or something more extreme) assuming the true group means were the same. In order to analyze data in a statistical package, it is usually necessary first convert your Access database or Excel spreadsheets into tables that can be read into statistical packages.

The minimum mean difference between the groups considered to be clinically significant. The sample size needs to be large enough to guarantee high power, usually 0.80 or more, to conclude that an effective active treatment is indeed effective while simultaneously holding alpha to a low level, usually 0.05 or less.   One approach to choosing how to summarize and graph your data is based upon the type of data you are summarizing. If the p-value is less than 0.05, we say that the group difference is unlikely due to chance and therefore is statistically significant. Click here for a video of how to import data into STATA. The following pair of variables has a correlation of about 0.9. Most statistical packages support at least two data types, numeric and character (text). Experimental design.
