Question
In a sample of 1000 students in a university, 125 of them or 12.5% are biology majors. The 12.5% is an example of statistical inference.
Solution 1
No, the statement is incorrect. The 12.5% is not an example of statistical inference. It is an example of descriptive statistics because it is simply summarizing the data collected from the sample. Statistical inference would be if we used this sample data to make a prediction or generalization about the population of all students at the university.
Solution 2
No, the statement is incorrect. The 12.5% is not an example of statistical inference. It is an example of descriptive statistics because it is summarizing the data collected from the sample. Statistical inference would be making predictions or generalizations about a larger population based on this sample. For example, if we were to say that approximately 12.5% of all students in universities everywhere are biology majors, that would be an inference.
