ProblemTypes
StatiBot assists you with a wide range of problems. They refer to differences,
relations, comparisons with expected values and distribution of data:
Differences
Two groups of data have different means. Are the differences meaningful?
How about if there are more than two groups?
Do the data of two groups vary in a similar way or are there meaningful differences in
variation?
How about if there are more than two groups?
Relations
Is there a relation between two properties that can be expressed with words
(categories)?
Is there a relation between two data series?
Does a quantity vary over time?
Is a quantity different before and after a specific treatment or event?
Comparisons with expected values
The mean of a data series is not as expected. Is the deviation meaningful?
Does a property that can be expressed with words (categories) occur with a given
frequency?
Distributions
Are the data distributed normally?
Is the distribution symmetrical?
