Types of Data
Give an example of a research question that includes an independent and a dependent variable. These are usually presented as, “How does A affect B?”, where A is your independent variable and B is your dependent variable. Describe the independent and dependent variables in terms of whether they are nominal (also called categorical), ordinal, interval, or ratio variables (interval or ratio variables are also called continuous variables). How would you study this research question?

Guided Response: Review several of your classmates’ posts. Provide a substantive response to at least two of your peers that demonstrates thoughtful reflection and analysis of the discussion in relation to their variables and research questions. Were their independent and dependent variables identified correctly? Was the variable type specified well? What would you ask them for further clarification?

Measures of Variability and Central Tendency
For this discussion, come up with 20 different data points (set of data) and enter them into the first column in an Excel spreadsheet. The data points can be any numbers you want as long as there are 20 of them. Your set of data should reflect one of the following criteria:

Create a set of data for which the mean is greater than the median.

Create a set of data for which the mean and median are equal but are different from the mode.
You will then use the descriptive statistics option in Excel, which is explained in Chapter 1 of your course text. You should get an output similar to Figure 1.2. This output must contain the following values: mean, standard error, median, mode, standard deviation, sample variance, kurtosis, skewness, range, minimum, maximum, sum, count. Begin your discussion by reporting your results for each of these values. Based on this output, which single value best describes this set of data and why? If you could pick three of these values instead of only one, which three would you choose and why? It is important to note that the answers to these questions may be different for each of you since you are each using unique sets of data.

The chosen research question is as follows; “How does one’s level of education affect the salary level” The dependent variable in this case is the person’s starting salary while the person’s education level can be considered as the independent variable for the research. This is because the level of education is the variable that has been manipulated to enhance the completion of the research process……………………
