Psychology Homework Discuss the strengths and weaknesses of the Milgram obedience study. Should the study have taken place? Milgram’s study is a very controversial study as it broke many ethical guidelines and has many methodological issues‚ but it also had many strengths. One strength of the Milgram study on obedience is that the experiment was reliable as it can be replicated and the results are consistent. The fact that the experiment was a Lab experiment makes the study even more reliable

Department of Business Administration Rosary College of Commerce & Arts 2013-2014 A simple random sample A simple random sample is obtained by choosing elementary units in search a way that each unit in the population has an equal chance of being selected. A simple random sample is free from sampling bias. However‚ using a random number table to choose the elementary units can be cumbersome. If the sample is to be collected by a person untrained in statistics‚ then instructions may be misinterpreted

RESEARCH Research is defined as the creation of new knowledge and/or the use of existing knowledge in a new and creative way so as to generate new concepts‚ methodologies and understandings. This could include synthesis and analysis of previous research to the extent that it leads to new and creative outcomes. This definition of research is consistent with a broad notion of research and experimental development (R&D) as comprising of creative work undertaken on a systematic basis in order to

Random sample It is often not necessary to survey the entire population. Instead‚ you can select a random sample of people/or firms from the population and survey just them. You can then draw conclusions about how the entire population would respond based on the responses from this randomly selected group of people. This is exactly what political pollsters do - they ask a group of people a list of questions and based on their results‚ they draw conclusions about the population as a whole with

Non-Probability Sampling: When the units of a sample are chosen so that each unit in the population does not have a calculable non-zero probability of being selected in the sample‚ this is called Non-Probability Sampling. Also‚ Non-probability sampling is a sampling technique where the samples are gathered in a process that does not give all the individuals in the population equal chances of being selected. In contrast with probability sampling‚ non-probability sample is not a product of a randomized selection

CHAPTER 1: INTRODUCTION AND DATA COLLECTION 1. The process of using sample statistics to draw conclusions about true population parameters is called a) statistical inference. b) the scientific method. c) sampling. d) descriptive statistics. ANSWER: a TYPE: MC DIFFICULTY: Easy KEYWORDS: inferential statistics 2. Those methods involving the collection‚ presentation‚ and characterization of a set of data in order to properly describe the various features of that set of data are called a) statistical

Let’s begin by covering some of the key terms in sampling like "population" and "sampling frame."
