The t-test allows you to say either "we can reject the null hypothesis of equal means at the 0.05 level" or "we have insufficient evidence to reject the null of equal means at the 0.05 level." A chi-square test allows you to say either "we can reject the null hypothesis of no relationship at the 0.05 level" or "we have ...

The basic difference is that Tables only display data in two dimensions. ... Matrix visualizations give the user more options to display data as a table. The user has the option to specify rows and columns, as well as layer the data to take advantage of Power BI's drill-down functionality.

A chi-square (χ2) statistic is a test that measures how expectations compare to actual observed data (or model results). ... For example, the results of tossing a coin 100 times meet these criteria. Chi-square tests are often used in hypothesis testing.

Chi-square Test. The Pearson's χ2 test (after Karl Pearson, 1900) is the most commonly used test for the difference in distribution of categorical variables between two or more independent groups.

You can think of the tabular model as a cross between a SQL Server relational database and an SSAS multidimensional cube. Like a database, the tabular model supports tables and their relationships. Like a cube, the model also supports measures and key performance indicators (KPIs).

The table, matrix, and list templates are built on the tablix data region, which is a flexible grid that can display data in cells. ... The key difference between tables and matrices is that tables can include only row groups, where as matrices have row groups and column groups. Lists are a little different.

The fundamental difference is a Value-Axis uses the X-Value to compute distance on the XAxis, whereas a Category-Axis uses the X-Index. Value-Axis are primarily used in scientific software where Category –Axis are typically used in financial software (e.g. stock charts).
