Sample size

A TTR evaluates the total number of different words used, or types, and the total number of words, or tokens, in a language sample. A TTR evaluates each participant’s use of a diverse vocabulary in each narrative. Each narrative was coded according to the Systematic Analysis of Language Transcription (SALT) Software Transcription Conventions (Miller, Andriacchi, and Nockerts…

Gastric Polyps A gastric polyp, also called a stomach polyp, is a growth on the lining of the stomach. Most polyps are not dangerous, but some can be harmful because of their size, location, or type. Polyps that can become harmful include: Large polyps. These can turn into sores (ulcers). Polyps that cause a blockage. A kind of polyp called an adenoma. This type of polyp can become cancerous. CAUSES Gastric polyps form when the lining of the stomach gets inflamed or damaged.…

concentration of DNA, protein, and carbohydrates in different homogenate samples, including heart, liver, and kidney of Bos taurus, while also looking for the diverse protein sizes found in each homogenate sample. The liver homogenate was then stored at -70°C. Of 300 µl, 5 µl of homogenate was placed into 2 µl of protein gel sample buffer. The homogenate was then mixed and heated at 80°C for 10 minutes. After heating, the sample was placed in a microcentrifuge…

relieve pain? What is known about population (the group the collected data is intended to describe), population parameters (a value calculated using all the data from the entire population), sample (a smaller subset of the entire population, ideally one that is fairly representative of the whole population), sample statistics, and bias (in favor or against something, unfair)? How representative is the data presented for determining whether magnets actually relieve pain? Is there anything that…

The Gallup World Poll, created in 2005, tracks the world’s most important issues by conducting studies worldwide that include 99% of the adult population. Some of the issues, for example, include “food access, employment, leadership performance, and well-being”(Gallup). The survey used consists of 100 questions, which are mostly global-based, but some “region-specific” questions. The same questions are asked for every country so statisticians can compare the data in each country every year.…

analysis of molecules such as DNA, RNA, and proteins, based on their sizes and polarity. DNA (deoxyribonucleic acid) is a molecule that carries most of our genetic information, and possesses a negative charge. During gel electrophoresis, DNA fragments can migrate through the gel also known as agarose when placed in a powerful electrical field. The rate at which the DNA fragments will move through the gel depends on their relative size. Horizontal gel slabs are commonly used on conducting gel…

the sample size by pollinating more flowers and collecting more stigmas might increase the likelihood of this being observed. Viable pollen was also observed in vitro by using the Brewbaker-Kwack medium protocol. Inducing germination of pollen grains showed that they were viable, especially in the higher sucrose concentrations (Figure 2). Lastly, pollen viability was observed with the use of FDA. The average of 26% of viable pollen could have been more reliable with increasing the sample…

lakes in fall of 2016 and collected samples from University Lake, Campus Lake, Bayou Lake, and College Lake. From these samples, chlorophyll levels and nitrate concentrations were measured. First, a chlorophyll determination test was done using a Büchner funnel. First a microfiber filter was placed into the Büchner funnel using forceps, then the paper was rinsed with 25 mL dH2O using gentle vacuum pressure. After this, the test tube was mixed and 50ml of the sample was filtered through the…

However, while there were strengths, the study had a few weaknesses as well with the design of the study. One weakness was the small sample size. Having a small sample size can have significant impacts on results. It can skew the data one way or the other, or it can result in no statistical significance. Conducting this study at more schools to gain a larger sample size would have been ideal in this…

paramount that sterile material and a meticulous clean technique is followed. Once samples have been collected, slices are produced and analysed under the microscope. There are several species of diatoms of different sizes, and they have to be identified and catalogued. The aim is to compare samples from the tissues with the water samples and see if the species found are the same. If the species identified on both samples match, this would mean that the deceased drowned in that water body. A…
