Comment on the statement given below: “Statistics is concerned with understanding the real world through the information that we derive from classification and measurement. Its distinctive characteristics is that it deals with variability and uncertainty which is everywhere”. ii. Read the Statement and identify which measurement of scale is used in statement with reasons? (a) Currently, many countries are suffering from COVID-19. Pakistan is also one of them. Many patients are in different conditions such as mild, moderate and severe illness. (b) The time is continuously passing aahead of seconds, minutes and so on; and is without a zero point of time. (c) entrepreneur conducts a survey with the employees to evaluate the degree of agreement with the company policies. In this survey 60% of the total employees agree with the policies, 10% just agree with some policies, 10% remain neutral. 10% disagree and 10% totally disagree with rules and policies
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
