Answer: Inferential statistics allow a researcher to make inference about a population of interest based on the observation taken on a smaller sample
Step-by-step explanation:
Statistics plays a vital role in the field of research. Statistics helps in collecting, analyzing and presenting of data. Statistical inference is the use of data analysis to predict the properties of a probability distribution. Inferential statistical infers properties of a population as the observed data set is gotten from a larger population.
The aim of inferential statistics is to derive conclusions from a sample and then generalize them to the population. The most common methodologies used are analysis of variance and hypothesis tests.
For example, if we want to know the examination scores of all the students in Egypt but it is not feasible to get the exam scores. So now we will measure the marks of smaller sample of students, of about 500 students and this sample will represent the large population of Egyptian students.
