Statistics Normal Distribution
In this module, you explore the normal distribution. A standard normal distribution has a mean of zero and standard deviation of one. The z-score statistic converts a non-standard normal distribution into a standard normal distribution allowing us to use Table A-2 in your textbook and report associated probabilities.
This discussion combines means, standard deviation, z-score, and probability. You are encouraged to complete the textbook reading and start the MyStatLab Homework before starting this discussion.

ANCOVA Analysis
A recent study of student anxiety suggested that test anxiety interfered with the effects of studying skills on student test performance. Students were classified as high or low in test anxiety based on responses to an anxiety inventory, then classified as high or low in study skills based on responses to a study skill scale. An overall measure of test performance was obtained by averaging the number of scores of three tests the students completed over the course of a semester. Enter the following data into SPSS and use anANCOVA to analyze the results.

Create Metric With Excel Data
Create a high standard metric showing the below. Show all pivot table fields and metrics/charts used in separate tabs if needed. .
How many total for each Creator ?
For each Creator how many have DEFAULT DOCUMENT TITLE in Title field out of the total they have done.
For each Creator how many have blank/null in Comments (b2Comments) field out of the total they have done
Translate the Creator id"field into a real name. Creator ID and corresponding name can be found in second tab. Maybe write a query that will pull the name from the second tab(creator name), just incase i add new Creator ID. So the metric should show Creator name instead of ID.
In the future , I will want to do the same thing multiple times by just copy and paste details into the excel sheet with headings remaining the same. Therefore, I am looking for a repeatable way to do this so all i have to do is paste new data and i can spit out or refres

The Discussion Question is:
Hamilton County judges try thousands of cases per year. In an overwhelming majority of the cases disposed, the verdict stands as rendered. However, some cases are appealed, some of the cases are reversed. The Enquirer conducted a study of cases handled by Hamilton County judges over a three- year period. Shown in the below links are the results for 182,908 cases handled (disposed) by 38 judges in Common Pleas Court, Domestic Relations Court, and Municipal Court. Two of the judges (Dinkelacker and Hogan) did not serve in the same court for the entire three-year period.
The purpose of the newspaper's study was to evaluate the performance of the judges. Appeals are often the result of mistakes made by judges, and the newspaper wanted to know which judges were doing a good job and which were making too many mistakes. You are called in to assist in the data analysis. Use your k

Discussion 2: Optimizing Sampling And Data Collection
The data that you collect from your norm group is called normative data. It allows you to see what the results of your test instrument should be, so that you have a standardized score against which to compare others. In other words, it allows you to equate scores across different tests of the same construct and lets you compare individuals to each other. Now that you have considered sampling the population of interest for your proposed test instrument, you explore how you might optimally define your sample and collect your data if you had unlimited resources. Though it may not always be possible for practical reasons to do this in real life, this exercise nevertheless provides you with a valuable thought experiment.
As you complete this experiment, keep in mind that even with optimal sample definition and data collection, test norms are not absolute. They can change with time or with a different norm group.
With these thoughts in mind:<
