PSY 325 Week 1 DQ 1 Data Analysis Updated

Data Analysis. For this discussion, you will organize data sets into meaningful number groupings, calculate basic descriptive values, and communicate written critiques of statistical analyses.

This exercise requires the use of a descriptive statistics calculator. You can find this tool in some versions of Excel (as part of the Analysis ToolPak) or you can use one of the many free online descriptive calculators such as the Descriptive Statistics Calculator by Calculator Soup.

To begin, come up with 20 different data points (that will form a set of data) and enter them into the first column of an Excel spreadsheet. The data points can be any numbers you want as long as there are 20 of them.

You will then use the descriptive statistics option in your descriptive statistics program or calculator. This is explained in Chapter 1 of your course text. You should get an output similar to the image in Figure 1.1.

This output must contain the following values: mean, standard error, median, mode, standard deviation, sample variance, kurtosis, skewness, range, minimum, maximum, sum, and count. Address the following points in your initial post:

• Begin your discussion by reporting your results for each of the values listed above.
• 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.

PSY 325 Week 1 Discussion  Updated

For this discussion, you will discuss your future career and how statistical analysis may be used in that field. In the Ashford University Library, find a peer-reviewed research study relevant to your chosen career and that presents statistical information to answer the research question. For your initial post,

State your future career and discuss how statistical analysis may be used in that field.

What types of projects might involve statistical analysis in your future career?

Summarize the article’s content and point out any statistical procedures you recognize from this week’s reading.

What research question did the authors investigate?

What variables did they use?

Did the article include any graphs or charts?

If so, what types were they? Did they help you to understand the information better? Why or why not?

2.         Question :       Rejecting the null hypothesis is the same as saying _____________.

3.         Question :       If the z transformation is used with population data, M is replaced bwhat symbol?

4.         Question :       How does the standard normal distribution differs from other normal distributions?

5.         Question :       A one-sample t value is statistically significant in which situation?

8.         Question :       The distribution of sample means refers to _______________.

9.         Question :       A distribution where the mean and standard deviation have pre-determined values calls for ________.

10.       Question :       If the mean of the distribution of sample means isn’t given, how is it determined?

PSY 325 Week 2 Quiz Set 2

Question :The table value z = .70 IS 2580. What percent of the population occurs below that point?

The z-test asks whether the population from which thesample was drawn has the same mean as the population to which it is compared True.

Question 3

4. Based on past experience, the probability that the sun will rise tomorrow is?

5   Rejecting the null hypothesis is the same as saying?

6 How many standard deviations below is 3 if z= -1.75

7   Degrees of Freedom refers to How many values can vary

8   If instead of z = (x – M) / s the formula is x = z(s) + M, what is the result?

9   How does standard normal distribution differ from other normal distributions?.

10 What is the similarity between the z test and one sample t test?

PSY 325 Week 2 Quiz Set 3

Based on past experience, the probability that the sun will rise tomorrow is ________.

The standard error of the difference is a measure of pooled variance.

The z scores is a ratio of difference to variability (t).

How is the z-test different from z-score analysis?

What advantage does the one-sample t offer over the z-test?

In a distribution for which the mean is 25 and the standard deviation is 5, what percentage of all scores occur at 30 or below?

Which is true of a one-tailed test?

The distribution upon which the z-test is based has a mean of 1.0.

In a distribution for which the mean is 25 and the standard deviation is 5, what percentage of all scores occur between 20 and 30?

The z-test asks whether the population from which the sample was drawn has the same mean as the population to which it is compared.

This Tutorial contains 2 Papers of this Assignment

Inferential Statistics Article Critique. Read the article “Differential Effects of a Body Image Exposure Session on Smoking Urge Between Physically Active and Sedentary Female Smokers,” and identify the research questions and/or hypotheses as they are stated. Consider the following questions: What are the variables (sample sizes, population, treatments, etc.)? What are the inferential statistics used in this article? Were the proper steps of hypothesis testing followed?

Write a two- to three-page paper presenting the information listed below. Include a title page and reference page in APA style. Cite any references made to the article within the body of the paper in APA style. Your paper should begin with an introductory paragraph (including a thesis statement) and end with a concluding paragraph summarizing the major points made in the body of the paper and reaffirming the thesis. When writing the article critique, your paper must:

Determine what question(s) the authors are trying to answer by doing this research

Determine the hypothesis being tested and the concepts that were applied in this process.

Evaluate the article and critique the statistical analysis employed in the study.

• Would you have included more and/or different variables? Explain your answer.

4. Examine the assumptions and limitations of the statistical study.

• What would you have done differently in this case? Why?

5. Identify how the authors applied statistical testing to the problem.

6. Interpret the findings of the author(s) using statistical concepts.

Standard Normal Distribution. For this discussion, identify the appropriate application of standardized scores to reflect on their benefits and to interpret how test scores and measures are commonly presented.

Review Chapter 3 of your course text, which introduces probability and the standard normal distribution. Examine the assumptions and limitations presented in these topics and then consider and discuss the following questions:

• This is an easy to understand video that takes you step-by-step through the basic hypothesis testing process. It is helpful for learning what a p-value is and how statistical significance works.

•   When comparing data from different distributions, what is the benefit of transforming data from these distributions to conform to the standard distribution?

•   What role do z-scores play in this transformation of data from multiple distributions to the standard normal distribution?

•   What is the relationship between z-scores and percentages?

•   In your opinion, does one do a better job of representing the proportion of the area under the standard curve? Give an example that illustrates your answer.
