Levels of Measurement for Each Variable in the Study In the survey that Debbie Horner, the Human Resource manager, distributed to the company, there are different levels of data available for analysis. The question seeking information about the respondent’s gender is a nominal-level question. “The nominal level of measurement observations of a qualitative variable can only be classified and counted” (Lind, Marchal, & Wathen, p. 10, 2011). For analytical purposes the order in which the data is displayed makes no difference. The question regarding the division of work for the respondent, and the question regarding if the respondent is a member of management or supervision is also nominal. Also, the question pertaining to length is service is nominal because it only seeks one answer. The ten questions relating to how each respondent feels is interval-level data. The ten questions ask each respondent to rate his or her individual feelings on a scale of one to five. One is considered very negative and five is considered very positive. This is known as a Likert Scale. The Likert Scale is the most popular form of survey data collection because it is easy to assemble, the scale is more reliable, and produce more interval-level data (Cooper & Schindler, 2011).
Data Coding After collecting the data, Sally, one the office support staff, began the task of coding the data. While some values were pre-determined other values needed coding. In addition to the questions there were also filter question asked such as gender, length of service, if the respondent worked as a supervisor or in management, and in which division each person works.
Questions 1-10
The questions numbered one through ten were pre-coded with assigned values one through five. A response of one indicates the respondent has very negative feelings, whereas a five shows very positive feelings. The team established that a response of two indicated the respondent’s feelings were negative. A response of three shows the respondent feels neutral. If the respondent chose the number four his or her feelings are considered positive. Sally coded the questions where respondents failed to answer as a zero. For the team’s analytic purposes all zeroes are coded no response.
Questions A, B, C, and D Question A asked each respondent the division he or she worked in. For coding, a number one is the food division. A response of two indicates the respondent works in the housekeeping division. When the respondent chose the number three that indicates he or she works in the maintenance division. Question B asked each person how long he or she has worked at BIMS. The survey asked each person to answer with years and months. To facilitate easier handling of the data Sally converted all years and months into total months. Question C requested that the individual indicate his or her gender. The answers were assigned the number one when the respondent indicates female, and the number two indicates a male. Sally also assigned the number zero to show where respondents did not wish to reveal his or her gender. The team has coded the number zero as no response, here, as well. Question D wants to know if the respondent works in management or supervision. The question only yields a yes, which is assigned the number one, and no, which is assigned the number two. Once again, some respondents chose not to answer this question and Sally coded those responses for the team as a zero. The team uses the zeroes in analysis as a no response again.
Cleaning the data When the surveys were completed and turned in Debbie had requested that Sally input the data for the team to analyze. The data input helped the team tremendously and saved the team time when analyzing the data. However, Sally admitted that she sometimes inputs data incorrectly. She stated that there were times that she may have input the number six when she meant to input a five. The team found, ironically, six instances where Sally input the number six instead of the number five.

#### Qualitative Critique

...A Critique of a Qualitative Research Article: Andropause Syndrome in Men Treated for Metastatic Prostate Cancer By Grand Canyon University NRS-433V Purpose of the Study Many people understand that women go through Menopause; it is not uncommon to hear a lady friend or a stranger say “there goes another hot flash” and then fan herself with whatever happens to be within reach. What many might be unfamiliar with is Andropause, or the equivalent of male Menopause. Andropause Syndrome in Men Treated for Metastatic Prostate Cancer: A Qualitative Study of the Impact of Symptoms (Grunfeld, Halliday, Martin, Drudge-Coates, 2011) , is a research article that talks about 21 men and their experience while undergoing androgen deprivation therapy (ADT) for treatment of metastatic prostate cancer. It is noted during this research that the participants experienced many different and debilitating symptoms. By exploring the feelings and symptoms of the men, it is the hope of the researchers that a positive impact can be made by professionals if they are more assertive in talking with patient’s about the effects of ADT treatment. When done, this can enable the patient to seek help with the side-effects whether it be medicinal, mechanical, or psychological (Grunfield, Halliday, Martin, Drudge-Coates, 2011). Literature Review Background. In this research article, 41 references were used with the majority of them being from other journal articles. This study takes place in the United...

#### Data Mining Algorithms for Classification

...Data Mining Algorithms for Classiﬁcation BSc Thesis Artiﬁcial Intelligence Author: Patrick Ozer Radboud University Nijmegen January 2008 Supervisor: Dr. I.G. Sprinkhuizen-Kuyper Radboud University Nijmegen Abstract Data Mining is a technique used in various domains to give meaning to the available data. In classiﬁcation tree modeling the data is classiﬁed to make predictions about new data. Using old data to predict new data has the danger of being too ﬁtted on the old data. But that problem can be solved by pruning methods which degeneralizes the modeled tree. This paper describes the use of classiﬁcation trees and shows two methods of pruning them. An experiment has been set up using diﬀerent kinds of classiﬁcation tree algorithms with different pruning methods to test the performance of the algorithms and pruning methods. This paper also analyzes data set properties to ﬁnd relations between them and the classiﬁcation algorithms and pruning methods. 2 1 Introduction The last few years Data Mining has become more and more popular. Together with the information age, the digital revolution made it necessary to use some heuristics to be able to analyze the large amount of data that has become available. Data Mining has especially become popular in the ﬁelds of forensic science, fraud analysis and healthcare, for it reduces costs in time and money. One of the deﬁnitions of Data Mining is; “Data Mining is a process that consists of applying data analysis and discovery...

#### Database Analysis and Modeling

...USE OF DATA ANALYSIS IN MODELING Use of Data Analysis in Modeling Michael Matthews CIS 331: System Modeling Theory Strayer University Mark O’Connell, PHD March 5, 2013 The term “model” refers to a process of creating a representation of reality and working with this simplified representation in order to understand or control some part of the world (Barker, Powell 2004 pg. 11). A model can be used in varies ways such as business plains, forming a database, or building a structure. It can also be formed mentally, visually, and mathematically especially by data analysis. Data analysis is the process of raw data measured in order to determine the means based on that data. Although, data is relevant in producing a model, it is only used to provide general perspective of information, not to form a solution. By determining this objective, I will demonstrate the use of data analysis to form a model and the advantages and disadvantages that come with it. The techniques of a model are used constantly to understand the world and to predict the outcomes and actions. For example, a mental model come into play when one manager has to decide is hiring an older worker beneficial to the company. Another manager suggests that hiring older workers is a good idea because they bring valuable experience to the job. This mental model is the basis of decision making, one action forming an outcome (Barker, Powell 2004). The decision that is made, the advantage and disadvantage of hiring...

...Problem 1: Data-Based Decision Making Supermarket Product Placement Suppose that we are responsible for managing product placement within a local supermarket.  Our shelving units have 6 shelves each and are numbered from 1 to 6—with 1 being the lowest shelf and proceeding upward until the highest shelf is assigned the number 6.  While there are many placement options that we should consider, we decide to look for any correlations between the row a product is placed on and its sales.  Since we have our data stored in a data warehouse, it is easily accessible and responds quickly to our data request.  Consider each of the following: ·         What judgments can you make regarding the placement of each type of product being considered? Answer - I think that we are more likely to place those items that are in higher demand by customers and those items that the company wants to generate the greatest profit from on the shelves that have the best sales ·         What is the consequence of making the wrong choice? Answer - Profit decreases, inventory doesn’t turn over ·         What types of products do you think each of the product groupings represent? Answer - Most likely to sell/greatest profitability to least likely to sell/lowest profitability ·         What target markets can you associate with each product group? Answer - ?
