For the results of the study conducted on the sample to be held true for the entire population, the sample should be a representative sample – that is, it should possess the same characteristics as the entire population, or as close to it as possible. A statistic is a characteristic that describes a sample; a parameter is a characteristic that describes a population.

The trend in the UK population is following an upward trend. From 61.8 million, the total population in the UK is reported to have reached 62.6 million in 2011 and again to increase up to 64.8 million in 2016.

On computing and comparing median for my town, Galion, this was $ 33,841 with that of Ohio, $45,395. It is clear that median is an effective measure as it divides the distribution into lower and upper halves. Given that an average of the data is likely to be affected and thus altered or influenced by extreme incomes in this case, it will be therefore not good to use mean as the measure of choice.

Font types and font sizes with which test questions are presented are identified to elicit different responses among students and readers in general.

Each of the corresponding values of X and Y designate a specific point on the graph and therefore when the points are all plotted they form scattered dots on the surface of the graph. This so formed pattern of plotted points scattered on the graph are attributed to the name of the graph, scatter plots.

Quantitative research confounds exist that influences research results against independent variables’ forces and therefore challenges implementation of quantitative research. History confound, maturation confound, and testing confound are examples of challenges to quantitative research.

Education providers have long been interested in determining the factors that influence student’s performance so they attain knowledge and skills essential to effectively contribute to community on a broader landscape (Kooi, 2008).

A cell membrane is a very important component of a cell because it is the one that controls the movement of substances in and out of a cell, hence protecting it from its environment. The experiment will be performed on a beetroot cell. To further explore the subject, recent experiments that have been performed with a similar purpose to the current study will be reviewed critically, and their findings linked to the findings of the current study.

To analyze critically, the most important components of the appraisal are an evaluation of the appropriateness of the study design to adequately deal on the research questions and a careful assessment of the key methodological aspects of the design. The other important aspects which should be analyzed are suitability of the statistical methods used and their subsequent interpretation, if there could be potential conflicts of interest and the relevance of a research to practice application.

The non-equivalent groups design would not effectively allow the teacher to determine if the quiz administration would improve learning. This is because the experimental design does not provide for the elimination or reduction of confounds that might affect the outcome of the exercise.

According to Montgomery (1997), this method helps in testing the significance of differences between classes by determining their variances.

The resulting organism is called “genetically modified” or “genetically engineered” product. The characteristics of genetically modified products are different from the characteristics of non-modified products. In 1994, Food and Drug Administration gave approval of the first GM food – Flavr Savr tomato.
