Sampling techniques: Advantages and disadvantages Technique Descriptions • Advantages • Disadvantages Simple random Random sample from whole population • Highly representative if all subjects participate; the ideal • There is no scope of personal bias • Each item has an equal chance of being selected • It provides more accurate and reliable data • It becomes possible to have an idea about the errors of estimation • Not possible without complete list of population members; potentially uneconomical

this claim by looking at a random sample of 50 stocks and finds a sample mean of 3.8% and a sample standard deviation of 1.1%. Using α= 0.05, does the analyst have statistical evidence to reject the claim made by the magazine? 2. According to Money, which not only looked at stocks but also compared them with real estate, the average appreciation for all real estate sold in the five years ending May 2007 was 12.4% per year. To test this claim, an analyst looks at a random sample of 100 real estate

1.1 create a plan for the collection of primary and secondary data for a given business problem. Primary Data Primary data can collect by using experiments, surveys, questionnaires, interviews, and observations. If you’ve already gathered this information, we can then analyze it and then come up with accurate results based on your needs. But if you haven’t already gotten this information together, no problem! We can also help with that step of data collection as well. (datacollectionservice.net

population. It is often used inmarketing research. In this technique, the total population is divided into these groups (or clusters) and a simple random sample of the groups is selected. The elements in each cluster are then sampled. If all elements in each cluster are sampled, then this is referred to as a "one-stage" cluster design. If a simple random subsample of elements is selected within each of these groups, this is referred to as a "two-stage" design. A common motivation for cluster sampling

Monte Carlo Simulation Using RiskSim 9 9.1 RISKSIM OVERVIEW RiskSim is a Monte Carlo Simulation add-in for Microsoft Excel (Excel 97 and later versions) for Windows and Macintosh. RiskSim provides random number generator functions as inputs for your model, automates Monte Carlo simulation, and creates charts. Your spreadsheet model may include various uncontrollable uncertainties as input assumptions (e.g., demand for a new product, uncertain variable cost of production, competitor reaction)

development and growth, reproduction, homeostasis, regulation and processing energy. When we view these together the eight items define life. Organisms and creatures are organized and coordinated structures that consist of one or more cells. Even the very simple, single-celled organisms and creatures are complex. Inside each cell atoms make up molecules, these atoms and molecules in turn make up organelles and other inclusions. In a multicellular organism or creature similar cells from tissues. These
