Statistics - One Question Hypothesis Testing
One-Question Hypothesis Testing enables you to determine whether a sample parameter has
changed or differs from a particular value. This situation, deemed a one group test, allows
you to compare the difference between your selected variable and a known value, which is zero
by default or can be defined when you set up the test.
