Pythagoras (560-480 BC), the Greek geometer, was especially interested in the golden section, and proved that it was the basis for the proportions of the human figure. He showed that the human body is built with each part in a definite golden proportion to all the other parts.. Statistics. What you will learn. Be able to state the null and alternative hypotheses for testing the difference between two population proportions.. Know how to examine your data for violations of conditions that would make inference about the difference between the two population proportions unwise or invalid.. Ratios. Comparison of two items/objects. Written one of 3 ways. As a fraction. With : (colon). . using word “to”. When writing a ratio. First thing you talk about is the numerator. Second thing you talk about is the denominator. In Unit 1, we learned the basic process of statistical inference using tests and confidence intervals. We did all this by focusing on a single proportion.. In Unit 2, we will take these ideas and extend them to comparing two groups. We will compare two proportions, two independent means, and paired data.. Lesson 5.2: Proportions. Chapter Five: Ratios and Proportions. Lesson 5.2: Proportions. Chapter Five: Ratios and Proportions.
