For this week’s assignment, you will present your answers to the following quest

For this week’s assignment, you will present your answers to the following questions in a formal paper format. Please separate each question with a short heading, e.g., normal curve, bell curve, etc.
Begin with a brief introduction in which you explain the importance of normal distribution.
Next, address the following questions in order:
Describe the characteristics of the normal curve and explain why the curve, in sample distributions, never perfectly matches the normal curve.
Why is the bell curve used to represent the normal distribution? Why not a different shape?
Why is the central limit theorem important in statistics?
What does the central limit theorem inform us about the sampling distribution of the sample means?
Imagine that you recently took an exam for certification in your field. The certifying agency has published the results of the exam and 75% of the test takers in your group scored below the average. In a normal distribution, half of the scores would fall above the mean and the other half below. How can what the certifying agency published be true?
Why do researchers use z-scores to determine probabilities? What are the advantages to using z-scores?
Conclude with a brief discussion of how the concept of probability might affect research that you might undertake in your dissertation project. In other words, how would a basic understanding of probability concepts aid you in analyzing and interpreting data?
Length: 4 to 6 pages not including title page and reference page.
References: Include a minimum of 3 scholarly resources.

Answer the questions below about your data adhering to the outlined criteria in

Answer the questions below about your data adhering to the outlined criteria in complete sentences. Cite any outside sources that are used. 500 to 1,000 words
1. Treat your data just as you would one of the datasets from the homework. Be sure you include appropriate measures of central tendency and dispersion etc.
2. Construct a frequency distribution using 5 –8 classes.
3.
Create 2 different but appropriate visual representations of your data (pie chart, bar graph, etc). You MUST use Excel to do this.
4 Complete the calculations for the 8 statistics you identified in your worksheet in week 3. You
MUST use Excel to do this.
5. Write a brief paragraph describing the meaning or interpretation for EACH of the statistics. For example, if some of the statistics chosen were the mean, median and mode, which is the best
measure?
6 Construct a 95% Confidence Interval to estimate the population mean/proportion in the claim.
7
Complete the calculations for the 8 statistics you identified in your What can you conclude from
this result regarding the topic?
8 Write up the responses to these questions in an APA paper between 500-1,000 words.

Using the research topics below, select your research topic. Here in discussion

Using the research topics below, select your research topic. Here in discussion board, title your discussion post by putting the topic you have selected in the subject line. Write a 200 word scenario that creatively describes the research topic you have selected. It is suggested that you complete this assignment by Wednesday of Week 1.
Below is a list of topics for you to choose from for your Research Project to be completed in this course. Select from this list only and in the subject line of your discussion board post, put your topic as the title. Each topic can only be selected ONCE. Please check the discussion board area before selecting your topic so that you do not duplicate a topic that has already been selected.
You may not make up or use any other topics except for the topics listed below. You will be conducting research using a t-test, which compares two groups.

Read the assigned chapters (PLEASE READ BOTTOM REFERENCES OF SUBJECT MATTER) and

Read the assigned chapters (PLEASE READ BOTTOM REFERENCES OF SUBJECT MATTER) and write a paper in which you answer the following questions and complete the following assignments:
Determine the major issues that must be addressed in item construction.
Discuss the general types of response scales used in measuring a construct and provide brief examples for each.
Indicate a more appropriate response scale that your instrument could use. Justify your use of the response scale.
Construct three sample items (even without the benefit of SMEs or a focus-grouped discussion) that represent your construct of choice. Include an appropriate response scale.
Use Rauthmann’s proposed item format taxonomy to analyze your partially-constructed three-item scale (i.e., point of reference, general item format, construct indicator, and conditionality).
Length: 5-7 pages, not including title and reference pages
