Introduction to Statistics

The study of statistics involves math and relies upon calculations of ______

Statistics are summaries or collections of ______

Statistics are often presented in an effort to add credibility to an argument or advice but they can be misleading and push you into ______ that you might find cause to regret

Identify a major flaw with the ______

A new advertisement for Ben and Jerry ' s ice cream introduced in late May of last year resulted in a 30% increase in ice cream sales for the following three months.Thus, the advertisement was ______

Like most people, you probably feel that it is important to “take control of your life.” But what does this ______?

Statistics provides tools that you need in order to react intelligently to information you hear or read. In this sense, statistics is one of the most important things that you can study. It will make you into an intelligent consumer of statistical claims. Step-by-step analysis of biological data Introduction to Statistics The statistical analysis of an experiment may be broken down into the ff.steps: Specify the biological question to be answered. Put the question in the form of a biological null hypothesis and alternate hypothesis. Put the question in the form of a statistical null hypothesis and alternate hypothesis. Determine which variables are relevant to the question. Determine the kind of variable each. Based on the number of variables, the kind of variables, the expected fit to the parametric assumptions, and the hypothesis to be tested, choose the best statistical test to use. Do the experiment. Examine the data to see if it meets the assumptions of the statistical test you chose (normality, homoscedasticity, etc.). If it doesn't, choose a more appropriate test. Step-by-step analysis of biological data Introduction to Statistics The statistical analysis of an experiment may be broken down into the ff.steps (______): Apply the chosen statistical test, and interpret the result. Communicate your results effectively, usually with a graph or table. Consider the following example. Then, apply the step-by-step analysis of biological data. Verrelli and Eanes (2001) measured glycogen content in Drosophila melanogaster individuals. The flies were polymorphic at the genetic locus that codes for the enzyme phosphoglucomutase (PGM). At site 52 in the PGM protein sequence, flies had either a valine or an alanine. At site 484, they had either a valine or a leucine. All four combinations of amino acids (V-V, V-L, A-V, A-L) were present. Step-by-step analysis of biological data Introduction to Statistics What is the difference between biological null and alternative hypotheses and the statistical null and alternative hypotheses? Step-by-step analysis of biological data Introduction to Statistics What is the difference between biological null and alternative hypotheses and the statistical null and alternative hypotheses? While the biological null and alternative hypotheses are about biological processes, the statistical null and alternative hypotheses are all about the numbers; in this case, the glycogen contents are either the same or different.
