What is the difference between a parametric and a non-parametric test?
Step by step
Solved in 2 steps
- Which lines or line segments or rays must be drawn or constructed in a triangle to locate its a orthocenter? b centroid?Write parametric equations for a cycloid traced by a point P on a circle of radius a as the circle rolls along the x -axis given that P is at a maximum when x=0.To locate the centroid of a triangle, is it necessary to construct all three medians?
- Discuss the difference between parametric and non-parametric tests. Justify your answer with suitable examples.In what instances do we use non- parametric tests? Explain all of themwe're conducting what are commonly referred to as non-parametric tests. But as you'll see, these are testing the same comparison scenarios that we've already been conducting throughout the semester. Now you need to elaborate on what the difference is between these tests and the ones we've already been doing? What is the primary condition that allows us to use these non-parametric tests? And how do these tests compare to their "counterpart" tests?
