1005 Words5 Pages

Have you ever come across statistics, whether about football stats or school ratings for your children and wonder how these numbers are developed? Statistics is the method of gathering, arranging, and explaining the data presented. It retrieves information from a study of a large quantity and presents facts, which can make things clear and understandable for the average person. When statistics are used for specific reasons they can be identified as descriptive statistics or inferential statistics. This course has taught me that these statistics can involve the following, hypothesis development and testing, selection of appropriate statistical tests, and evaluating statistical results. This paper will explore the two types of statistics and …show more content…

Descriptive statistics provide a straightforward summary, according to data samples and its’ measures. It plainly lays out what is happening within the data. According to B. Conner and E. Johnson in American Nurse Today, “They help us understand and describe the aspects of a specific set of data by providing brief observations and summaries about the sample, which can help identify patterns” (2017, p.1). I have learned that there are three common types of measures of location used, which are mean, median and mode. The mean is the total of all numbers being identified divided by how many numbers there are. It is the best measure you can receive because it incorporates all data values. The median is the number that can be found in the middle of the set of information. When there are two numbers identified as the middle value the average of both numbers is used. Finally, the mode is the most frequently occurring value in the data set and can be more than just one …show more content…

In hypothesis testing, the ANOVA, T-Test, or Chi-Square is used to investigate if a hypothesis’s mean is true or false. Hypothesis testing involves developing the null hypothesis, choosing the suitable test static, identifying the statistical significance, deciding the decision rule to reject or not reject the null hypothesis, and collecting the data and completing the required calculations. The null hypothesis is simply a statement, which the investigator comes up with, that is being tested. Static testing involves using a value that is consistent and is computed from the data, such as the mean or mode. It measures the similarity or dissimilarity between the data and the null hypothesis. Statistical significance is measured by conducting a test, for example, a T-test, which tests the mean of two sample populations. Whether the null hypothesis is rejected or not depends on whether the test results are in favor of it. Finally, all the data needed for the test is collected to complete the

Plankton Activity Postlab 1) Apply 2.5: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. Explain how the abundance of phytoplankton in the pond depends on the abundance of an abiotic resource such as nitrogen. - Phytoplankton are the producers in the pond. Species of organisms in ecosystems have their own carrying capacity relative to other species, and carrying capacities are determined by particular abiotic and biotic resources in an ecosystem. An increase in nitrogen levels in the pond (e.g. from fertilizers) will result in a dramatic increase in phytoplankton levels, but once phytoplankton population reaches its carrying capacity (determined by availability of other resources besides nitrogen, [DO] levels, predation etc.),

Similar to the use of ethos, statistics can also be utilized to add to the credibility of the writer and writing. In the article, statistics are used to give specific evidence supporting claims made by Summers. For instance, Summers makes his claim that plastic bags are in fact better for the environment and he uses evidence to back up his opinion. He says, “Compared to paper bags, plastic grocery bags produce fewer greenhouse gas emissions, require 70 percent less energy to make, generate 80 percent less waste, and utilize less than 4 percent of the amount of water needed to manufacture them.” The statistics used support Summers and illustrate the differences between plastic and paper bags.
