Descriptive statistics is the type of statistics that probably springs to most people’s minds when they hear the word “statistics.” In this branch of statistics, the goal is to describe. This is alpha (α), which is most often 0.05; therefore, a P-value less than 0.05 is typically considered statistically significant. If we are unconcerned about the direction of any difference between groups, H1 will simply be ‘the two populations are different’ and we will use a two-tailed test. Descriptive statistics can only be used to describe the population or data set under study: The results cannot be generalized to any other group or population. There are two kinds of descriptive statistics that social scientists use: Measures of central tendency capture general trends within the data and are calculated and expressed as the mean, median, and mode. Is the sample biased? Independent variables would be risk factors for heart disease: cigarettes smoked per day, drinks per day, and cholesterol level. So was I at first. If the inference concerns the 100 widgets, the statistics observed are population statistics. A type I error occurs when H0 is incorrectly rejected. While a point estimate gives you a precise value for the parameter you are interested in, a confidence interval tells you the uncertainty of the point estimate. The learner's task is to use this sample to form representation of the class or population of widgets. Figure 11-1 illustrates what could happen when we take a sample from the population. Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. Definition: Inferential statistics is a statistical method that deduces from a small but representative sample the characteristics of a bigger population. However, such an analysis is not suitable for series with less than 20 points, as serial dependence and other factors will contribute to an overinflated alpha in such cases (Greenwood & Matyas, 1990). Thus, the larger the sample of subjects, the more powerful the statistic is said to be. As you recall, these are values that represent an average of a collection of values, such as average age or standard (which is really “average”) deviation from the mean age. This is clearly a kind of inductive inference in that it is not guaranteed to be correct: The inspector's past experience makes the conclusion probable but not certain. Let us focus on the group that makes up the sample. Kuhar, in Encyclopedia of Animal Behavior, 2010. That value along with the degrees of freedom, a measure related to the sample size, and the rejection criteria are used to determine whether differences exist between the treatment groups.
