SECTION 1: Descriptive Statistics (Ch.1-4) Does the order of your birth - whether you are first, second, third, etc., among your siblings - affect your life? Imagine that you are a researcher studying whether a person's birth order has any effect on his or her life outcomes; specifically, you're looking at whether it helps predict the person's annual income. In order to study this topic, you sent out a survey to n = 10 highly successful people, asking them four questions: 1. What is your annual income? 11. What year were you born? Are you an only child? IV. What is your birth order within your family? Each of these four questions will become a variable in your data. For each of these four variables, decide whether it is Nominal, Ordinal, Interval, or Ratio, and explain your reasoning for each answer. Here are a few hints: . There is one of each (one Nominal variable, one Ordinal variable, one Interval variable, and one Ratio variable). So, you should not have any repeat answers. . For the variable of "Birth Year," you might be tempted to say Ratio. However, remember that the difference between Interval and Ratio variables is that Ratio variables have a true zero point - zero really means a complete absence of what you are measuring. But think about Birth Year.. if you follow it all the way down to zero in your mind...the year 2020...the year 1900....1800...down to year zero...does "Year Zero" really mean an absence of time, or the beginning of time? No, it doesn't, it's just where A.D. to go B.C. So, Birth Year does NOT have a true zero. Question 1. a. Is "Annual Income" nominal, ordinal, interval, or ratio? b. Is "Birth Year" nominal, ordinal, interval, or ratio? C. Is "Only Child" nominal, ordinal, interval, or ratio? d. Is "Birth Order" nominal, ordinal, interval, or ratio
