t-Tests and ANOVAs In Chapter 9, we learned how to conduct a t test of a hypothesis when we were testing the mean of a single sample group against some pre-determined value (i.e., the 21.6 gallons of milk consumption as the national average). This week, in Chapter 10, we will see how to test hypotheses that involve more than one sample group—such as testing to see if males are significantly taller than females. If we have two groups, then the technique that we will use will still be a t test

discrimination, when whites are discriminated against and minorities are being discriminated for, doesn't make it right. Affirmative action legalizes discrimination (Steele 1990, 39). "I thought discrimination was illegal in this country (Buchanan 1995, 1)." Also, if this discrimination continues racism in the United States may become worse. Imagine what you would feel like if you couldn't get a job just because you are a white man and not a hispanic man. The racism will become worse because

ordinal, interval and ratio. Distinguishing between these types of variables is important, as several statistical tools may only be used for certain types of data. Nominal variables: where values are assigned to categories in no particular order. This assignment of values is arbitrary and holds no particular meaning or order to them. For example, “sex” where 1=male 2=female “marital status” where 1=never married 2= married 3=defacto “yes/no type questions” where 1=yes 2=no

rates but of course, we don’t know whether or not we’ll hit our targets! A data table can show us at a glance the effects of missing and/or exceeding our target numbers. In a new Excel spreadsheet create an area to hold our assumptions. You can create this region yourself, or download the sample spreadsheet. We need figures in year ‘0’ (the current year) for Revenues, Expenses, Revenue Growth, and Expense Growth. We include the year of interest at the bottom so that we can quickly change the year

my data set I want to look at the relationship between officers and crime. Maybe the best way to complete this is to look at population. My initial hypothesis is that the size of the city is going to determine the number of officers. This means that my alternative hypothesis is that there is no connections between the size of the city and the number of officers. The intuition behind this is that the larger the city in square miles, the more officers we need patrolling the area. Moreover, it

remove any previous versions of the add-in. Excel will not work correctly if you try to use two versions of the same add-in simultaneously. For example, if you were using a tryout version and now you want to use the standard version, Excel will regard this as two versions of the same add-in. The same applies to moving from an older to a newer version, such as from SensIt 1.31 to SensIt 1.45. If you were using the previous version by “opening” the add-in file, then all you need to do is not open that
