Basic Concepts of Statistical Studies 1 Introduction s Decision makers make better decisions when they use all available information in an effective and meaningful way. The primary role of statistics is to to provide decision makers with methods for obtaining and analyzing information to help make these decisions. Statistics is used to answer long-range planning questions, such as when and where to locate facilities to handle future sales. 2 Definition s Statistics is defined as the
CHAPTER ONE INTRODUCTION Background of the Study It is generally accepted in the world that pupil’s performance is directly influenced by the instructional materials applied. These instructional materials are the key ingredients in learning. Barnett (1992) comments that teachers should cover the materials in the curriculum and prepares pupils for standardized tests. This may have happened in western countries because of adequate resources. Nevertheless these instructional materials have not been
Determinants of poverty INTRODUCTION Background to the study The translation of consumption into welfare units is a function of various physiological characteristics such as age and sex of recipient, and environmental factors ( The possession of assets is a measure of the socio-economic status of the household. According to the 2002 Uganda Population and Housing census main report, majority (79%) of the households owned the houses they lived in especially in rural areas with 86% compared to urban
sides of the specimens prior to the drawing process and placed in the Hille press using the 3 centering arms to centre the sample in the correct position. The four specimens were then drawn using the 10-ton Hille Press with a clamping pressure of 5 tons/in2 at different predetermined draw lengths. The 4.0’’ non-marked specimen was only half drawn, with the remaining samples fully drawn. Finally, the thicknesses of the cups were measured at the same locations as prior to forming and recorded. RESULTS:
Question 1. 1.1 Types of interview: • Telephone interview • Face-to-face interview • Panel interview • Group interview • Sequential interview • Lunch/dinner interview • Formal/informal interview Telephone interview: Regularly companies ask for a phone interview before welcoming you in for a face-to-face interview so as to show sign of improvement comprehension of the kind of applicant you are. Face-to-face interview: In face to face interview done by you and one of company employee or two
4.3.1 Mixed Methods There are various different research strategies with distinctive characteristics available from which a researcher may select, based on the previous criteria. Yin (2003) and Saunders et al. (2009) recognized that granting numerous research strategies occur, there are great commonalities amongst them and henceforth the significant contemplation would be to choose the greatest useful strategy for a particular research study. Some of the typical research approaches used in business
Also, Figure 2 displays the link between perceived social pressure from family and time spent participating in aerobic exercise per week. The relationship between these two variables was very weak and insignificant, r(206)= .04, p=.558, as summarized in Table 1. The threshold significant p-value for data is p<.05. From our data, we can conclude that the weak correlation between social pressure from family and the amount of time spent on aerobic exercise is likely due to chance and is therefore
Research and Design This study will use a true experimental design because it allows the researcher to exercise better control over research variables. This design ultimately strengthens the inference of causality. To prove with confidence that changes in the dependent variable were caused by the independent variable rather than sampling error, the research design must meet three criteria (Nieswiadomy, 2012). The three criteria are: 1) the researcher manipulates the experimental variable; 2)
Traditional techniques for sampling and estimating population characteristics require that sample selection is done with a known probability. However, for a hard to reach population this is impossible. There is no list or registry from which to create a sampling frame or if there is a list, a random sampling can yield low number of eligible respondents since it’s often non-representative of the intended target population.1 In addition, it can be extremely difficult to locate members of this population
been studying diseased remains for centuries and collecting and maintaining donated samples for more than a hundred years (Westfall et al 36). Today these places are called biobanks. Biobanks are institutes that collects and maintains donated samples of human blood, tissues, and any other collectable genetic material for the purpose of research (Westfall et al 37). At first biobanks were small and collected samples for specific study purposes. Records were kept in a notebook and specimens were stored
