1. What are the similarities between descriptive and inferential statistics? What are the differences? When should descriptive and inferential statistics be used?
Descriptive statistics describes data by organizing factors of a sample such as culture, gender, age, or location and is shown with charts or graphs. Descriptive statistics can interpret larger portions of data and reduce larger portions of data. The measure of central tendency describes the average score being the mean, the median being the midpoint of a spread of scores, and the mode the most frequent. There are certain levels of measurement and descriptive statistics may not be the best technique based on the measurement, these scales include nominal, ordinal, interval, and

The analysis of a single individual, event, or group is a case study. There are different types of cases, which are intrinsic, instrumental, and collective. When doing this type of research one must go out into the field to observe or interview in a natural setting. In the field, those collecting data develop a research role, which establishes the position of the investigator and his or her relationships with others in the situation. At one extreme, the researcher is a complete outsider, totally detached from the naturally occurring behavior and activities of the participants. He or she essentially has no involvement in what occurs in the setting. The researcher is detached coming in, collecting data, and then leaving. A complete insider, on the other hand, is a researcher who has an established role in the setting in which data are collected, engaging in genuine and natural participation. Most fieldworkers’ roles are between these extremes, using what could be labeled insider/outsider or partial participation. These individuals participate to some extent in the setting, rather than just sit on the sidelines, but they are not full participants. Case studies provide in-depth information about people and the possible insight into behavior, in which these can be more controlled at a later time. These types of cases provide opportunities for new techniques. Case studies also make it possible to research rare phenomena. Case studies provide

Descriptive statistics are digits that are used to summarize and describe a given range of data (Klenke, 2008). Basic descriptive data includes, mean, median, mode, variance and standard deviation. The data can be rearranged in an ascending order as follows:

The third resource that I used is from the Office of Justice Programs/Bureau of Justice Statistics (BJS). A specific article titled “Intimate Partner Violence in the United States” shows a graph of intimate partner violence rates declining from 1993 to 2006. The article is quite vague, with no real description or stats stating whether or not men commit more violence against women than women do against men. “Violence between intimates is difficult to measure because it often occurs in private, and victims are often reluctant to report incidents to anyone because of shame or fear of reprisal” (S. Catalano).

I will now be explaining the five roles of research and giving an example for each one of the roles. The five roles of research include: research to inform policy or practice, research to extend knowledge and understanding, research to improve practice, research to aid reflection and allow progress to be monitored and finally research to examine topics of contemporary importance.
These methods include descriptive statistics and bivariate analysis. There are two measures of descriptive statistics; they are central tendency and measures of variability or dispersion. Descriptive statistics helps to summarize data gathered throughout the research. In addition, it happens to be one of the easiest forms of statistics to interpret and it is more meaningful. It also provides the chance for a pattern to emerge since it is easy to show and summarize. Furthermore, it manages to simplify a significant amount of data in a practical fashion. Statistics gathered by this method would generate valuable information on all the measured

When analyzing data, such as the marks achieved by 100 students for a piece of coursework, it is possible to use both descriptive and inferential statistics in your analysis of their marks. Typically, in most research conducted on groups of people, you will use both descriptive and inferential statistics to analyses your results and draw conclusions. So what are descriptive and inferential statistics? And what are their differences? Descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. Descriptive statistics do not, however, allow us to make conclusions beyond the data we have analyzed or reach conclusions regarding any hypotheses we might have made. They are simply a way to describe our data.
HLM Cruise Lines has been under intense media scrutiny as of late due to our unethical practice of releasing untreated wastewater into the oceans. As the world's second largest cruise company, it should be our duty to protect the waters upon which we sail. Therefore, I would like to be released from my current duties in order to research alternative methods of managing the waste produced on our ships. At the conclusion of my research, a formal report will be provided to you.

Quantitative and Qualitative are said to be systematic in different design. Both design have to follow a process system that involved defining a principle of research.
At the beginning of this subterm, I had a limited understanding of the proper research methods used within psychology. Despite having previously completed several psychology courses, two being upper level courses, there was still much I needed to learn pertaining to psychology research methods. While this research class has been on only an introductory
