I want to present two people, Henry David Thoreau and a vegan. Thoreau was an American Romantic who decided to go to the woods to live off the land, so he spent a year at Walden Pond hoeing beans and watching the water to show that anyone can sustain themselves on a small budget and nature while a vegan abstains from consuming any animal products. What do they have in common? Stereotypically, vegans are outspoken and obnoxious, and for some, Thoreau is annoying and irrelevant. Yet they share a…

Have you ever wondered if there could be an easier way to lift heavy objects without all the ropes, claws and wheels? Well not anymore, ever since the hydraulic crane which uses the force of water and pushes or pulls throughout the pipes and pulls up heavy items. This has been an innovation in the pulley and regular cranes. With something good there is one bad, if a person were to use pipes or steel which one would be more sustainable and last longer? As in all the other cranes this specific one…

One major survey administration method is phone surveys. The phone survey method is one where the researcher calls individuals who comprise his or her sample and then has them answer the survey questions over the phone (Chamberlain, 2016). This has historically been a popular administration method, as it has several advantages, i.e., it is quick, cheap, and effective (Chamberlain, 2016). That being said, there are several disadvantages as well. For example, individuals have become less…

meeting that customer satisfaction was a concern the employees were voicing. This discussion led to the potential of performing a survey throughout our ten locations, which serve over two-hundred customer per day. The quandary is how we build this sample. When gathering satisfaction data from a population, such as the customers of a popular clothing store, surveys are very beneficial. However, there are two different survey methodologies used, which are population studies and sampling. Both…

Studies and information gathered from the population offers a valuable tool for a marketing manager to utilize when one is trying to increase wine sales in an operating establishment. Many studies exist, which concern factors shown to influence dining satisfaction such as the quality of food, the quality of the service, as well as the environment and ambiance. However, nominal research exists, which focuses on the customer’s satisfaction with wine when they are in a restaurant atmosphere, while…

a) Sample selection size varies for each experiment, depending on how large the whole group under investigation is or how much time it would take to sample a certain group (Rathburn, MacConnadchie, Zizler, Hill, & Moorman, 2012, p. 72) . Sample selection is important part of a studies experimental design because it usually decides how valid a study is. The validity of the sample size and study is usually decided through the peer-review process, which is one of the reasons why the peer review…

1. “When investigating a large population, it is often impractical and usually unnecessary to measure all the elements in the population of interest. Typically, a relatively small number of subject or cases is selected from the larger population.” (McMillian, 2012, p.96) According to McMillian (2012), population is a target you want to study to develop knowledge and to create action plans to assist those individuals. An example is when a researcher use a group of students with autism to find out…

The two-sample t procedure is appropriate to use in this experiment in order to see if there is a difference in the two population means of stride length in the two different species, N. rattus and N. squamipes. This is because the boxplots appear to be roughly symmetrical, as well as, both normal quantile-quantile plots look roughly linear. Considering two-sample t-procedures are quite robust to violations of the normality assumption, the t-procedure will likely perform well in this…

This sample method was chosen over the other methods as it involved asking random people the questions from the questionnaire. This saved us time as we were able to ask a group of students in different classrooms and this made it easy for us to get 100 responses each. We had asked type types of…

primary caregivers to adolescent insecure attachment, intending for a working model of attachment and metallization during adolescence (Boreli, Snavely, Compare, Decio, 2014). Although the study used robust sampling methods, it used a low-risk Italian sample population (Boreli, Snavely, Compare, Decio, 2014) which limits broader application. Therefore it only allowed for investigation on the link between neglect and attachment security, and could not confirm causation. The Research Ethics Board…
