Design of experiments

researcher has. One method is utilizing experiments as defined by Merriam Webster (2016) it is “a scientific test in which you perform a series of actions and carefully observe their effects in order to learn about something”. A researcher in emergency and disaster management (EM), could run many types of experiments to try to mitigate the results of a disaster. One type of experiment is the classic experiment, the classic experiment also referred to as a pure experiment, takes place in some…

“It is the weight, not numbers of experiments that is to be regarded”1. As Sir Isaac Newton, one of the most influential scientists in history, states – the design of an experiment is very important. Therefore, aspiring scientists must learn about many different types of techniques and its applications. Over the past six weeks, students were exposed to six experts discussing different fields of research but their studies contained many overlapping qualities. Some common topics discussed were…

Introduction The experiment will be working with diffusion and osmosis; it will test if the starch will travel through the semi permeable membrane (dialysis tube) causing osmosis. Diffusion is when a substance is highly concentrated turns into a lower concentration, and is evenly distributed throughout. An example of diffusion is when you cook and the smell of food flows until it in dynamic equilibrium; which is the even distribution of the substance. Osmosis is the movement through a semi…

could have been achieved by the manipulation of the positive pairing rather than the actual liking of the DE100 logo itself. The DE100 experiment had a simple and straightforward design which would be easy to replicate. It is not time consuming, therefore, boredom is avoided for the participants and therefore, it is cost effective for the researcher. The experiment allowed for the replication of the Chen et al. study to appreciate that the manipulation of one thing (positive pairing) could have…

The device and tray are then placed under a stereomicroscope for analysis. Lighting for experiments is provided by a 1000 lumen LED lightbulb. Usage of an LED lightbulb ensures that minimal heat will be introduced to the device and the output of light remains constant, ensuring that all pictures are exposed to the same degree of lighting which…

Tucker performed science in action by performing an experiment with skin tissue in order to determine the gene responsible for formation of the skin features. Example two relates to Lab #11, “Diversity and Adaptation”. “Skin organs” are relatively small features that allow organisms them to eat, survive, and…

My View on Statistics Statistics, the all encompassing, universal method of scientifically verifying and studying individuals and their characteristics. The applications of Statistics in any field be it finance, psychology, computer science, ecology, etc. never ends. “Big Data” as some would call it defines the scientific driven decisions of modern companies (The Age of Big Data, Lohr). Statistics uses any type of data to describe a characteristic of many individuals in a population. This…

Videogames have been distracting young children from reality for decades while simultaneously allowing them to learn a multitude of skills. A case study which exemplifies these characteristics was conducted on a 4 year old biracial girl who sustained second and third degree burns to her shoulders, neck, chest, forearms, and her left thigh caused by an accidental scald injury (Sil et al, 2012). Yet, she remarkable had no damage towards her face along with no complications with her motor, hearing,…

The question investigated in this experiment was how does the sow bug’s preference of habitat affect the concentration and distribution of the organisms. The purpose of this investigation was to decipher what habitats these organisms prefer to live in and how it would affect their population density. This was tested by a simple experimental design with four petri dishes that each represented a different environment. The control treatment was the dish with just dirt while the other habitats…

Attitudes toward cheating behavior in college students Academic success is determined by many factors; effort, ability, and time to name a few. But one factor, one that not many consider, can drastically change the outcome of an individual’s success. Cheating persists throughout all levels of education, whether administrators want to admit it or not. The problem with cheating is that it commonly goes unnoticed, and there are many factors that influence the probability of this occurring. One of…
