(2016). IBM SPSS statistics 23 step by step: A simple guide and reference(14th ed.). New York, NY: Routledge.For this three-part assessment, you will create and interpret histograms and compute descriptive statistics for given variables; analyze the goals of data screening; and generate z-scores for variables, analyze types of error, and analyze cases to either reject or not reject a null hypothesis. You will use SPSS software and several course files to complete this assessment.By successfully completing this assignment, you will demonstrate your proficiency in the following areas:Analyze the computation, application, strengths and limitations of various statistical tests.Analyze the strengths and limitations of examining a distribution of scores with a histogram.Analyze the relevant data from the computation, interpretation, and application of z-scores.Analyze real-world application of Type I and Type II errors, and the research decisions that influence the relative risk of each.Analyze the decision-making process of data analysis.Analyze meaningful versus meaningless variables reported in descriptive statistics.Apply the logic of null hypothesis testing to cases.Interpret the results of statistical analyses.Interpret histogram results, including concepts of skew, kurtosis, outliers, symmetry, and modality.Interpret descriptive statistics for meaningful variables.Apply a statistical program's procedure to data.Apply the appropriate SPSS procedures for creating histograms to generate relevant output.Apply the appropriate SPSS procedure for generating descriptive statistics to generate relevant output.Apply the appropriate SPSS procedures for creating z-scores and descriptive statistics to generate relevant output.Communicate in a manner that is scholarly, professional, and consistent with expectations for members of the identified field of study.Communicate in a manner that is scholarly, professional and consistent with expectations for members of the identified field of study.IBM SPSS Statistics Standard GradPack.

Bellevue University Calculating Sell Thru and Penetration Sell Thru Questions
Calculating Sell Thru allows businesses and managers to determine the percentage of units sold compared to the total amount originally on hand.Calculating Penetration of product styles, product types, vendors, etc., allows managers to identify and reorder best sellers, and to take action to address slow-selling, less-profitable products. What ultimately influences results are the actions that businesses take, based on analysis of the information gathered from the data and the thought processes used to make decisions.Scenario A:The buyer ordered 1,200 units of seasonal garden items and planned for a 35% sell thru in the first month.All 1,200 units were received in the stores 4 weeks ago.Of the 1,200 units, the sell thru on garden hoses was the highest and the stores in warmer climates sold more garden hoses during the first four weeks.The current inventory report shows 400 units of the seasonal garden items on hand.Scenario B: The buyer ordered the garden hoses from several different vendors.Vendor A - $90,500 in salesVendor B - $80,000 in salesVendor C - $40,000 in salesThe total garden hose category had $400,000 in sales for the quarter.Instructions:Use the information in the scenarios provided above to answer the following questions:
Scenario A: Calculate the sell thru of seasonal garden items in the scenario and include your calculations in your answer.Scenario A: Analyze the scenario in order to provide justification when answering the following questions:Is sell thru "good" or "bad", as compared to the buyer's plan?What can the sell thru data tell the buyer?How should the buyer respond to the sell thru data?Why is it important to know which stores are trending up/down in seasonal garden item sales?Scenario B: Calculate the penetration in dollars for each of the vendors and include your calculations in your answer.Scenario B: Analyze the scenario in order to provide justification when answering the following questions:What is each vendor's dollar penetration rate (percentage) and what can the penetration rate for each vendor tell the buyer?Considering the available information, what recommendations would you make regarding reorders for each of the vendors?What other information would you need about the garden hoses and/or vendors to allow you to make wise decisions on reorders?Summarize the results of your analysis of the two scenarios to explain the importance of using sell thru and penetration calculations to aid in managerial decision-making. Justify your explanation.Compose your answers with a minimum of one paragraph per question (a - e), for a minimum of 5 paragraphs total.Research and use at least one additional outside source to support your recommendations
