Given that the primary focus of my research involves crime rates‚ the level of measurement required is interval. As interval level of measurement describes variables that have differences between them numerically. Therefore‚ all crime rates are interval level measurements. The purpose of content validity is to measure the significant variables within the research. Further it can be used to quantify the adequate sampling of substance areas of questionnaires to determine content relevance. Content

Assignment in Research Methods 1) Overview of various research methods When writing a Research Paper it is important to know different research methods. These methods help to gather and systemize the information and data in order to scientifically prove the validity of the work. Further will be explained ways how to collect the data. Research methods are divided in two big blocks: quantitative and qualitative. Quantitative methods are those where results are explained in numbers‚ whereas

Introduction Qualitative research and quantitative research are two approaches that are usually used by researchers to conduct research. The concept of a ‘mixed method’ approach is to combine the two approaches together. But the concept applies to using more than one qualitative method to conduct a research since each brings a particular kind of insight to a study (Ritchie and Lewis‚ 2003‚ p38). This paper aims to examine whether the three approaches---observation‚ interview and questionnaire‚ are
