Statistical dispersion

Chapter Ten Analyzing and Reporting Qualitative Research Qualitative data analysis has it is own nature which is different than the quantitative data. Qualitative and quantitative data are different in the process of both the analysis and interpretation. Mostly qualitative data is textual the goal of which is to deeply understand the relationships rather than just explaining. Qualitative data analysis is iterative and involves member checking asking experienced informants to assure the…

practical exercises of the course. The journey began with descriptive statistics; measures of central location and dispersion. The very common measure of central tendency; mean, median and mode. Whereas variance and standard deviation were discussed as measure of dispersion. I 'm also actively participated in doing the exercises for both measure of central tendency and dispersion using hypothetical data given with the lecture. Furthermore, the lecture continue with hypothesis testing…

R² = 0.449 means that the best fit equation for the data shows a correlation lesser of 50%. It therefore indicates a somewhat "weak" relationship hence not a good fit. Figure 5: Good fit: Residual plots showing a random pattern A key part of statistical modelling is examining residuals. By carefully looking at the residuals, assumptions become either reasonable or unreasonable which in turn determines whether the model in itself is appropriate. Residuals are the differences between the…

intend to offer final and conclusive solutions to existing problems. Descriptive research design :> Descriptive research is also called Statistical Research. The main goal of this type of research is to describe the data and characteristics about what is being studied. The idea behind this type of research is to study frequencies, averages, and other statistical calculations. Sample Designing :> After defining the problem . Do work on research design and determine how to collect the data.…

unconditional inclusion that we look, act, and think at least somewhat like our family. Our actions and beliefs reflect our families and expose differences between them and other families. These differences help to classify families and assign certain statistical trends to them as well. Whether your family is large or small, far or near, it is classified according to the components that make it unique. Classifying family types can help us better understand what is expected of us. The first…

CHAPTER THREE METHODOLOGY HYPOTHESES/RESEARCH QUESTIONS 1. The hypothesis of the research paper is “The improvement of Civil-Military cooperation will enhance humanitarian assistance efforts”. 2. This research will answer the question about: a. What are the factors that can influence Civil-Military cooperation in disaster relief? b. Are existing civil–military frameworks (at policy, strategic and operational levels) sufficient? c. How can Civil-Military cooperation in disaster relief…

What does risk and return mean to the average investor? In order to answer this question, investors must first look to themselves to determine the correct steps to take. One cannot call him or herself an investor without first measuring their risk tolerance as well as risk capacity. Risk tolerance represents how much a client is willing to withstand swings in the value of held assets as well as changes in general market conditions. One of the most common ways of measuring one’s risk tolerance is…

Meeting in Bretton Woods, New Hampshire in July 1944 representatives of 44 countries drafted and signed the Articles of Agreement of the International Monetary Fund (IMF). Taking lessons from the economic meltdown of the interwar period, the Allied countries wanted to develop an international monetary system that would facilitate full employment and price stability simultaneously allowing each country to attain external balance without restricting international trade. Bretton Woods proposed…

Introduction It is known that air pollution had adverse effects on the health of those exposed to it. There is a diverse mix of air pollutants and the most common pollutants in outdoor air include carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), ground level ozone and particulate matter (PM) (1). Outdoor air pollution is a mixture of gases and particulate matter (PM) of varying sizes and it is often difficult to isolate the source of the PM from all the possible sources of…

thirty and three hundred, and there resulted in four dependable data points. These four data points were required to be converted into PFU/ml so they could be easily compared to the bacteriophages original titer. The average was the first of the statistical tests done and this required the student to add the four PFU/ml data points up and then divide by four. Standard deviation is the next statistic that was required to solve and the students had to pick between sample or population standard…
