A comparison distribution type is what we use to make inferences from the data of our study or experiment. The researcher uses the comparison distribution to determine how well the distribution can be approximated by the normal distribution. Hypothesis testing is very important for every statistical test.

Why you use z distribution?
A z distribution allows you to standardize different scales for comparison.
What differentiates a probability from a probability distribution?
A probability indicates the likely-hood that a particular event occurs out of a set number of observations or measurements. A probability distribution allows relative comparison of probability of an event with any other possible event.
What is the purpose of doing the z-score?
The Normal distribution is frequntly encountered in real life. Often a matter of interest is how likely it is that the random variable (RV) being studied takes a value that it did or one that is more extreme. This requires a comparison of the observed value of the RV with its Normal distribution. Unfortunately, the general Normal distribution is extremely difficult to calculate. The Normal distribution is defined by two parameters: the mean and the variance (or standard deviation). It is impossible to tabulate the distribution of every possible combination of two parameters - both of which are continuous real numbers. However, using Z score reduces the problem to that of tabulating only one the Normal distribution: the N(0, 1) or standard Normal distribution. This allows the analysis of an RV with any Normal distribution.
What is relative performance appraisal method?
According to SHRM, the comparative method is when the appraiser directly compares the performance of each employee with that of others. Some comparative methods are Ranking, Paired Comparison and Forced Distribution.

What is ethnology?
The study of language of a specific ethnic group within a culture.
What is the difference between main switch and distribution board?
The switch turns the supply on and off whilst the distribution board takes the incoming supply and separates it into the various loads - lighting, cooker, shower, sockets, etc. In modern domestic electricity supplies the distribution board usually incorporate a mains switch but in the earlier days of electricitythe switchwould be mounted separately from the 'fuse box' because the materials used were quite bulky in comparison to modern alloys and plastics.
What is an faulty comparison?
A comparison that is not realistic.
What information do you get from a ratio comparison that you don't get from a difference comparison?
you get 2 sets of numbers in a ratio comparison and you only get one in a difference comparison
What does the student's t-distribution refer to in statistics?
The Student's T- Distribution is a type of probability distribution that is theoretical and resembles a normal distribution. The Student T- Distribution differs from the normal distribution by its degrees of freedom.
