An optometrist suspected that the reading habits of all the first year optometry students from DDC have a bad effect to their eye vision that could possibly affect both of their academic and non-academic performance. Upon conducting the study, he found out the following results; 1. 75% of the total number of first year optometry students from DDC, 25% were males and 50% were females, have bad eye vision due to their reading habits and got poor academic performance but a satisfying performance in non-academic activities. 2. The researcher got a 30% sample out of the 100% population and found out that 20% of the sample were females and 10% were males with bad eye vision due to their reading habits and got poor academic performance but satisfying non-academic performance. 3. The conclusion was, the reading habits of the first year optometry students from DDC had bad effects to their eye vision. This was one of the reasons that the students have poor performance in academic activities only. QUESTIONS What do you think is the branch of statistics that the optometrist used in his research? Why? If the total population of first-year optometry students from DDC is 65, how many students from the population have bad eye vision due to reading habits? How many females and males of the total population have poor performance in academic activities?
