A convenience sample is formed when we select elements from a population on the basis of what elements are easy to obtain. Sometimes a convenience sample is called a grab sample as we essentially grab members from the population for our sample.

Solution: A. Increase in population of our country in the last two decades. B. Number of tables and chairs in a classroomSolved Example Question: As only 3 students came to attend the class today, find the probability for exactly 4 students to attend the classes tomorrow. Solution:The mathematical average is known as the mean of the data set, whereas the positional average is considered the Median. The difference between Mean and Median is understood by the following example. In a school, there are 8 teachers whose salaries are 20000 rupees, a principal with a salary of 35000, find their mean salary and median salary.Both are key in data analysis, with parameters as true values and statistics derived for population inferences. The key difference between parameters and statistics is that parameters describe populations, while statistics describe samples.
