Critical Appraisal of Quantitative Research Introduction Abstract. The abstract consisted of one paragraph, total of ten sentences, which includes the purpose, design, sampling, and results. Researchers expanded on results but did not include conclusion. Relevant information such as sample size, study design, measure outcomes, and results were included. Problem. New nurse graduates are leaving their first employment at a high rate in Taiwan. There is a high shortage of nurses in Taiwan,…

sophisticated machine learning techniques such as Lasso Regression and Random Forest Regression. In that project, I dealt with a huge data set with more than 1500 cases and 82 variables. I implemented some dimension reduction techniques to find out the most useful variables. After picking up all relevant variables, I eliminated some outliers using graphs and finally found the relationship between house price and those explanatory variables. The project was very complicated but it helped deepen…

information about the attitudes, beliefs, experiences, or behaviors of a group of people. The experimental method, also known as the experiment, is the only research method that can be used to identify the cause and effect relationship between two or more variables. I am going to do a research on gender differences on alcoholism. The participants…

Stage 1 Biology Practical Report Isabelle Bury C2 Surface Area : Volume ratio Introduction: A cell is described as the basic unit of all living things and is commonly known as a building block for these living organisms. Cells are considered the fundamental unit of life as it relates to the metabolic processes occurring which allow organisms to stay alive. Cells are responsible for providing structure within organisms, absorbing nutrients from food sources and converting nutrients into energy.…

environments as they generally reside under rocks or logs, in its crevices. Their tendency to reside in habitats with high humidity also predicts their preference to be in darkness. The independent variable in this environment is the change in environment: dark or bright light. The dependent variable is the number of isopods in each chamber at the given time, which in this lab is every 30 seconds. Constants include the temperature of the testing room, humidity (wetness of filter paper) and…

the demographic variables that influence the perceptions of faculty members toward the organizational justice. In particular, the demographic variables include the occupation of the faculty members, rank, experience, and size. Various analyses are performed on the data, including descriptive and inferential analysis. Notably, the measures for occupation, rank, and the perceptions of faculty members are categorical variables that are measured at the ordinal level. These variables are treated as…

explores the interaction of variables within a quantitative research. A variable in research can be an individual or group, which is observed for various measurements during an experiment (Creswell, 2014). Additionally, variables used within an experiment is used to observe the reactions of how each variable interacts with each other and the dependent variable. The effects of each variable help determine the outcome of a study or experiment. In order to understand the variables, they must first…

The participants from each age group were selected at random. The experiment took place in a quiet class-room with adult supervision so that there are no distractions for the participant. Only the participants age was recorded for this experiment. In the first situation the participant was asked to read words…

students and provide them with valuable knowledge. One research study that I previously participated in at Indian River State College in my honors statistics course was the islands project. The online islands project allowed students to collect a random sample from hundreds of people on separate islands and in separate towns. On this online site students were able to conduct study’s on the people they randomly selected such as provide them with food, alcohol, drugs and many other things then…

Merrell Dow Pharmaceuticals was a company that had a drug out on the market known as Bendectin. It was advertised as a medicine that would help expecting mothers with the morning sickness that came from their pregnancy. However, it was later found that taking this pill while someone was pregnant might cause problems for the baby upon birth because it might affect the child while it was developing in the womb. Daubert was one of those that were affected by the medicine. They claimed that the drug…
