Primary methodologies are ways we gather information when conducting social research. There are multiple types of useful methodologies in collecting qualitative data like interviews and a focus group as well as quantitative data like questionnaires, surveys and statistical research for examples. There are many advantages …
This hypothesis will require research proving or disproving the question of mental illness causing a person’s chance of becoming homeless to increase. I will first locate an area with a high volume of homeless individuals, as this research will include all genders and races. The …
Using qualitative data collection method, it rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories. They produce results that are easy to summarize, compare, and generalize. Quantitative research is concerned with testing hypotheses derived from theory and/or …
Science is a venture that builds and organizes knowledge in the form of testable explanation and prediction about what are the things that is happening in the world. A closely related meaning of this is Aristotle’s scientific view, which is scientific knowledge is a body …
Microscopes and the field of Science are two inseparable things. Almost all Sciences are associated with the use of a microscope, a device use to view objects which are not visible to the naked eye. The term microscope came from the Greek term “Micros” which …
Non Parametric Test is a kind of statistical test that was discovered by Wolfowitz. This test covers a variety of categories and these are the independent samples, dependent samples and the variables relationship with co- variables. To contrast and differentiate measurements is a hard thing …
I really appreciate the way you listed the steps in selecting random samples. I did not come across any steps or rules to obtain a simple random sample. The lottery Is a form of simple sampling. It does not use any method to select numbers …
Repeatability measurements were taken on a bolt to get the total length, and also measuring the low rate of a faucet by measuring the amount of time it took to fill a beaker. To ensure a more accurate sample, twenty measurements of each section were …
It makes use of the tabulated critical values for different confidence levels in which the resultant value for the said test hould not exceed, otherwise the datum is considered invalid and cannot be included in the course of the following calculations. Where Xq is the …
Quantitative research can be carried out in an unnatural, artificial environment so that a level of control can be applied to the exercise. This level of control can be achieved through laboratory experiments that allow comparing with the real world results. Also the results allow …
Random Sample: each member of the population has the same chance of being selected Representative Sample: characteristics should represent those of the target population without bias Observational Study: no intervention by the investigator, no treatment imposed Experimental Study: Investigator has some control over the determinant …
Objective There are many websites and newspapers giving predictions in this direction, but there is no tool which can give mathematical analysis about the races. For my Data Mining Project I will use a database collected from www. Greyhound-data. Com, then I will use this …

Research can be generally described as the systematic enquiry that seeks answers to a problem or the methodical study that seeks to prove a hypothesis which aims to refine existing knowledge and generate new knowledge. Consecutively, we encounter research in our everyday lives. In fact …
Descriptive and Inferential Statistics The world of science would find itself lost without research. Research alone however, oftentimes will not answer the questions or solve the problems that scientists set out to solve. Statistics is where research becomes applied and scientists can make educated guesses …
Consider the Luxury Seaside Hotel Risk Management case you put together in your previous assignment. Answer the following questions regarding each one of the risk sources you have identified (at least 4). i)If you desired to follow a statistical approach in the assessment of the …
The basic steps of the scientific method are: 1) make an observation that describes a problem, 2) create a hypothesis, 3) test the hypothesis, and 4) draw conclusions and refine the hypothesis.
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
In science, a hypothesis is part of the scientific method. It is a prediction or explanation that is tested by an experiment. In the study of logic, a hypothesis is an if-then proposition, typically written in the form, "If X, then Y."
