). It may have been the case that the students participating in the first study were all honor students, whereas the students in the second study were students of varying ability levels. For example, a drug company publishes in a magazine a study that found positive results from the use of their knee-joint supplement, but does not publish a study that found negative, or even dangerous, results from use of the same supplement. Statistics analyze data to discover the truth. For example, one study shows that students who reviewed for the sat examination for five or more hours, scored in the top 10 of the students taking the test in the spring of 2013.
In addition, since it may be the case that the majority of the twilight saga movie-goers were teenagers, the sample may have already been biased toward a particular genre of literature. Statistics can be influenced by a multitude of factors. In one state, 52 of the voters are republicans, and 48 are democrats. This is equivalent to finding the probability that p is less than zero. How is this possible? Shouldnt statistics always arrive at the same results concerning the same issue? Not necessarily.
What is the probability that the survey will show a greater percentage of republican voters in the second state than in the first state? The proportion of republican voters in the first state, p the proportion of republican voters in the sample from the first state, and p the proportion of republican voters in the sample from the second state. When dealing with data, it is possible that different statistical studies, concerning the same issue, can arrive at very different results. It may be the case, that developments since the date of the survey will contradict its findings. A second study, also relating to the spring of 2013, showed that reviewing for the sat examination did not result in scores in the top 10. In a second state, 47 of the voters are republicans, and 53 are democrats. Data can be collected through numerous methods, such as observations, interviews, questionnaires, databases, samplings or experimentation. A good deal of time should be given to this step as it is the most important step in the process. The number of voters sampled from the first state (n make sure the sample size is big enough to model differences with a normal population. To find this probability, we need to transform the random variable (p , we find that the probability of a z-score being -0. Further research concluded that this was not true, and that second-hand cigarette smoke contains cancer causing agents and is unsafe.
