What struck me as most interesting in Chapter 1 was how much thought actually goes into preparing studies and experiments. For instance, I was surprised when I read about how surveys were designed. I was not aware that the wording of questions could have such an effect on the results of the survey, and was shocked to read that only 27% of Americans approved of “government censorship” of media sex and violence while 66% approved of “more restrictions on T.V.” As a result, I realized how powerful certain words could be, since tweaking the wording just the slightest bit had such a major effect. Having answered dozens of surveys in my life, I never realized that question wording could be considered a bias, since it can subtly lead those in the sample to a certain answer. This made me wonder, are there other types of biases in surveys, such as someone in the sample giving an inaccurate answer? What also surprised me was the idea of random sampling. Before reading my chapter, I didn’t realize that those preparing surveys went through so much trouble in choosing whom to survey. I always thought that they would survey those around them for convenience, but I now realize that would be biased because not everyone in the population would have an equal chance of being in the sample. I now understand how precise they have to be in order to ensure that the results of the survey are unbiased so that they can draw conclusions about the population. It makes sense that they would want a random sample, because if everyone in the population did not have an equal chance of being in the sample, the sample would not represent the population and the results would be useless. This brought up a couple of questions. Does the size of the random sample affect how accurate the results are? My best guess is that the larger the random sample the more accurate the results, because variation within the sample would increase, thus better representing the population. Also, if you had a small population that was easily accessible, would you survey the entire population as oppose to taking a random sample of the already-accessible population? Are there different types of random sampling? What happens if the person chosen to be in the sample does not respond? The preparation of experiments also struck me as very interesting. I took great interest in the concepts: placebo effect and double blind procedure. I was able to personally relate to the placebo effect. A few months ago, I had a raging fever and I took Motrin as a result. I “felt better” a couple hours after I took it, but later realized that the medicine was actually expired. Obviously I didn’t feel better because of the medicine, since the active ingredients must have been too weak to have any effect on my immune system. I must have just believed that I was getting a treatment and thus, my spirits were boosted and my symptoms were relieved. A question that rose was: Is the idea of the placebo effect present in other aspects besides medicine? The idea of the double-blind procedure also made sense to me. It is a very good way to avoid the placebo effect, since neither the evaluator nor the subject/experimental unit would know the independent variable being implemented, so neither of their expectations wouldn’t produce an effect. Are there any other ways to avoid the placebo effect? Is there such thing as a single-blind procedure where only the evaluator knows what the treatment is? Would it be as effective as the double blind procedure?
