Descriptive statistics

in four classes at a fitness club. Steinberg et al. state, “217 persons were tested during the six or seven sessions” (p. 273). Use of the word “or” makes us wonder if Steinberg et al. knew how the sampling took place. They go on to state that statistics used to prove the hypothesis were taken from those participants who attended five or more classes. Comparing this sample to the population as a whole, is inappropriate since those who felt negative moods after exercise were not likely to attend…

2. Demonstrate which tests have improved, which have gotten worse, and which have stayed the same. If any tests have gotten worse, please explain why you think this has happened. If any tests have improved, that are NOT the component that you have been working on, please explain why you think this has happened. (2) All my test have improved except my BMI and my waist-to-hip ratio. To explain, my BMI has increased by 0.2 because my weight increased due to the fact that I gained muscle mass.…

After testing the D. magna with alcohol, the results showed a negative effect on the D. magna. After recording the normal heart rate in beats per minute (bpm) before the experiment, alcohol was applied to four different D. magna for each percentage of alcohol. The three concentrations of alcohol used were 5%, 10%, and 20%. Once the differences in heart rate were recorded for each of the D. magna, the averages of the four differences in heart rate for each concentration of alcohol were calculated…

To determine differences among the three groups, the researchers used a (3 groups x 2 phases) analyses of variances. Initially, the researchers looked at the number of AR quizzes passed in high, middle, and low readers across both the baseline and intervention phases of the study. Then, the book levels read by the three varied groups were studied across both phases. Last, differences were examined for significance. The data revealed that the high group passed more AR quizzes than the low group.…

This artifact is primary based on sample rates and to see the effects of sample rates by using Sinusoidal waves. Sinusoidal waves can be represented using frequency and period. The Frequency of a Sinusoidal wave is the number of complete cycles that happen in a particular period of time or in a given sample. The Period in terms of Sinusoidal waves, is the time it takes to perform one complete cycle. The Sinusoidal wave is a series of identical cycles happening repeatedly. The sample rate is the…

My assessment of the IT division of Fig Technologies in Tyler Texas is as follows. The company has sent one individual from each of the three offices Qatar, Germany, and Texas to other offices for a period of two months to learn the differences of the way. They were to learn the culture, process and systems. The differences between the three cultures are as follows. Texas, is a very diverse culture also known as a melting pot, they have a mixture of most every culture. These different cultures…

Analysis of variance (ANOVA) is a process that is used to compare three or more population means at the same time (Donnelly, 2013). In this scenario, Mi Casa Front Porch restaurant is looking to better understand customer satisfaction levels. A student intern assisted Mario of the Mi Casa Front Porch restaurant with some data analysis from three different locations. Mario also recognized that there are two distinct customer types that frequent the three locations. Unfortunately, the student…

Raw class data between scaling variables and maximum jumping performance were recorded in Table 1. These combined results were then studied using both the regression and correlation analysis methods to predict which morphological traits (body size, mass, muscle length and muscle circumference) determined the source of variation in toad locomotor performance; with the longest jump distance of the toads as the dependent variables and the various scaling variables as the independent variables. Then…
