Sample Descriptive Essay

by low statistical power. As stated above, a power analysis was unable to be conducted for this study. Grove, Burns & Gray (2016) state: Low statistical power increases the probability of concluding that there is no significant difference between samples when actually there is a difference (Type II error, failing to reject a false null) (see Chapter 8 for discussion of the null hypothesis) (Groove and Cipher,…

the managers need analyzed information, which could be provided by statistic method. AJ Davis department store, a chain store, wants to analysis the credit customers so the sample data of 50 credit customers was collected. The manager at the store has speculated some information about credit customers. By using the sample data of 50 credit customers, along with hypothesis testing and confidence intervals, we could determine whether manager’s speculations are convincing. Also, this report…

There are different types of parametric tests to determine if a statistically significant difference is present. An independent-samples t-test is used when comparing two groups on one continuous dependent variable that is normally distributed. A paired-samples t-test is used when you look at the differences of one group across two time periods or observation periods. ANOVA tests are used when we are examining more than two groups or more than two observation periods. Slide 3: Our null…

• PSO Algorithm to generate test cases A. Initialize the population with N Particles where Program will search for optimal solution through the movement of these particles. And Set iterations counter I = 0. B. Apply Fitness function: Calculating the fitness value by calculating the percentage of this particle will share in minimizing the total processing time to find the optimal solution. C. Compare the calculated fitness value of each particle with its (lbest). If current value is better…

Methodology: Subject selection criteria were kept as following: No other medical history and associated disability such as autism, CP, ADHD etc ,normal middle ear condition, average intelligence children / average scholastic performance, children with hearing impairment using cochlear implant or hearing aids having experience greater than 2 year have taken in the research study. In cochlear implant subject must have at least 15 active electrodes[ 26 ](Purdy 2005). Behavioural screening test…

Question How does changing the size of the airplane affect how far the airplane goes. Hypothesis If we change the size of the airplane then the paper airplane will go further. Materials Paper, graph paper, meter stick, a pencil, Procedure: 1.I will build two identical paper airplanes. One will be my control airplane that is smaller and the other will be my test airplane the one that is bigger. 2.I will throw my control plane 10 times and I will use a meter stick to measure the distance of…

Article Critique In the article, Case management to reduce risk of cardiovascular disease in a county health care system, Ma et al. (2009) acknowledge that given the hundreds of billions spent in addressing the cardiovascular disease (CVD), embracing innovative approaches is necessary to supplement the conventional healthcare models. Besides, they recognize that the CVD, along with its causative factors, affects individuals across different ethnic, social class, and racial groups. However, they…

As sample size decreases, so does confidence in the estimate and accuracy of findings. The small sample size (n=60) meant that a number of categories has cell totals of less than five but also more than two levels. Thus neither the planned Chi Square nor the secondary Fisher’s exact tests could be conducted for items with these characteristics. Additionally, the method of recruiting participants (through the researchers’ networks and through the university) meant that the sample may have been…

This journal article review will look at the information presented, and determine whether or not the findings by the author are consistent enough to merit additional research. The sample of this study consists of forty-two children from New Zealand, ages eight through twelve. Their parents were also a part of the sample, as their results were highly reciprocal of their children’s results, and vice versa. The participants were selected from schools in Dunedin, New Zealand, as part of a broader…
