Most of us find it hard to determine our sample population to be used in conducting our research. We hardly identity how many of the total population shall we take as our sample. Worry no more, for there is a very reliable way to solve for the sample size. This is what I have learned when Dr. Ava explained to us the topic on Sampling Theories and hypothesis testing. We can use the Slovin's Formula in determining the sample size of the population.
Dr. Ava also emphasized to us the proper way of testing the hypothesis. Before, I really don't understand what a null hypothesis is. I've heard a lot about it but I don't know what it is. Since Dr. Ava explained to us about it, I can now easily test hypothesis based on given data and situations. Reject or accept? Well, it depends on the result of the tcomputed and ttabled. If tcomputed is lesser than ttabled, then accept the null hypothesis. If the tcomputed is greater than the ttabled, then reject the null hypothesis.
