Week 1 Assignment Worksheet: Examine the Data for Errors
You will now have the opportunity to become re-acquainted with SPSS, review some of the basic statistics used in Statistics I, and enhance APA format when presenting statistical results.
The following small data set is from a study conducted within a single middle school. Fundamentally, this study is a comparison of the differences between male and female teachers in personal Confidence Scores and was conducted to determine if a relationship exists between the number of Years of Experience and Confidence Scores. The researcher wants to examine if years of experience could be used as a predictor of confidence scores and if gender could also impact confidence scores.

Using scholarly writing and proper APA format, complete, and then submit the following:
Please open the SPSS file confidence scores. Once you have opened the file, please follow the instructions below. As a statistician, it is your job to make sure that there are no special circumstances with the data that could lead to confusing or misleading results. Specifically, the data used for analysis is equal to the data collected.
I. Examining the data for accuracy
1. Identify the level of measurement of each of the three variables.
2. Identify the dependent and independent variables.
3. Use SPSS to conduct the necessary descriptive statistics on each of the variables based on their level of measurement (e.g., frequency distribution, mean, median, mode, standard deviation, standard error, boxplots, etc. Hint: not all of the three variables require the same descriptive procedures).
4. After examining the data with descriptive statistics, did you find any issues with the data?
5. If your answer was yes, what procedures will you do as a researcher to make sure that the data in SPSS, is the same as the data collected in the original spreadsheet (Hint: You dont need any calculations to do this.)
6. Once you have addressed the issues with the SPSS dataset, please repeat the necessary descriptive statistics on each of the variables based on their level of measurement (e.g., frequency distribution, mean, median, mode, standard deviation, standard error, boxplots, etc. (Hint: Not all three variables require the same descriptive procedures.)
