Directions: Identify the random sampling method used in each item. 1. You are given a list of all graduating students in your school. You decide to survey every tenth name on the list and ask in which organization they belong. 2. You wish to make a comparison about the gender differences on Mathematics performance. You divide the population into two groups, male and female, and randomly pick respondents from each of the gender. _3. You assign numbers to the members of the population and then use draw lots to obtain your samples. _4. You randomly pick five out of fifteen barangays to where to conduct your survey in your municipality or city. 5. You write the names of each student in pieces of paper, shuffles and then draw eight names.
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.
