Before conducting a statistical analysis, every researcher needs to measure the depended variable. The measurement depends on the type of variable. Different types are measured differently. So, the researcher has to decide on the appropriate scale of measurement. There are typically four levels of measurement: nominal, ordinal, interval, and ratio. 1. The purpose of the nominal scale is for identification and represents the lowest level of measurement. With a nominal scale, the researcher only

Failing to make to the JV soccer team has been one of most impactful moments of my life, and it has changed the way I approach athletics and life outside of sports. For most of my life, I was skilled in organized sports, especially soccer, which I had played for many years. After a successful soccer season my freshman year, I thought that I would make the JV team for sure. At tryouts, I went through the motions of each drill. I breezed through the conditioning tests, doing the bare minimum for each

INTRODUCTION BREAST cancer is currently the most common cancer affecting women worldwide [1]. In European women, it is the leading cause of cancer death, causing one in six of all deaths from cancers [2].In the U.S., a woman has a 12.15% (about one in eight) risk of developing breast cancer during her lifetime[3]. Mammography is one of the most reliable and effective methods for detecting breast cancer at it early stages [4]. In developed countries, population-based mammography screening programs

False Positive Drug Test Background Erika A. Alvarez – C03087541 University of Miami False Positive Drug Test Background Drug testing is one action an employer can take to determine if employees or job applicants are using drugs. It can identify evidence of recent use of alcohol, prescription drugs and illicit drugs. Currently, drug testing does not test for impairment or whether a person’s behavior is, or was, impacted by drugs. Drug testing works best when implemented based on a clear

Many online auction sites help consumers bid on items they might want to possess. These sites include eBay, WebStore, ebid, OnlineAuction, OZtion, Overstock, and a whole slew of others. Currently there is no system to protect consumers from fraudulent sales. When someone bids for an item, consumers trust both the seller and the online auctioneer to be both honest and ethical when presenting items for bid. Many of the auction houses, including Sotheby's and Christie's have their experts examine

Automated Fingerprint Identification Systems (AFIS) in law enforcement and border control applications has heightened the need for ensuring that these systems are not compromised. While several issues related to fingerprint system security have been investigated, including the use of fake fingerprints for masquerading identity, the problem of fingerprint alteration or obfuscation has received very little attention. Fingerprint obfuscation refers to the deliberate alteration of the fingerprint pattern

Article Critique In the quantitative study by Turid Moller and Olav Linaker (2010), they examined and compared records of information given by psychotic patients concerning their alcohol and drug problems. In their study, the research question is "Do psychotic patients under-assess themselves during early clinical interventions and what are the effects of under-assessment on their treatment outcomes?" The null hypothesis is that failing to diagnose and account for substance abuse will not lead to

Researchers routinely choose an ◊-level of 0.05 for testing their hypotheses. What are some experiments for which you might want a lower ◊-level (e.g., 0.01)? What are some situations in which you might accept a higher level (e.g., 0.1)? An alpha level of 0.05 is arbitrary and was set as a standard by scientists. One of the key concepts in hypothesis testing is that of significance level or, the alpha level, which specifies the probability level for the evidence to be an unreasonable estimate.

A focus group instrument is used when it is well suited to the subject matter in question by listening to the opinions of others in a small and safe group setting before they form thoughts and opinions. An A typical focus group is between 6-12 homogeneous people who share similar characteristics or common interests. Focus groups generally reveal what each person within the group truly feels on the subject which provides credibility to the study. The facilitator is key to promoting an accepting
