This article used the appropriate statistical procedures for the study. Using descriptive statistics and Pearson’s correlation allows the researcher to reveal if any correlation coefficients among variables are found. Also, using the path analysis to find the relationships among the variables was a key factor. The sample was significant for the study and the path analysis model because it required a large number of cases and this study had 2,565 participants. The responses from the survey allowed…

When faced with an analysis of a situation which deals with a population, an analyzer will incorporate both descriptive and inferential statistics to evaluate his or her results and create a credible conclusion. Descriptive statistics provides information focused on an immediate group of data. After defining what needs to be analyzed, the descriptive statistics will help the analyzer abridge the data to a more meaningful and comprehendible form, which will then provide patterns in his or her research…

Before proceeding with any statistical procedures, I conducted a preliminary analysis using descriptive statistics and frequency analysis. Both were used to assess the characteristics of the data, check for violations of assumptions underlying the statistical techniques, as well as address research specific data requirements (Pallant, 2013). Using frequency analysis, I checked the minimum, maximum, and range of the categorical variables to identify errors and address the same. Additionally, I examined…
Descriptive statistics is appropriate in this case, because of its ability to evaluate the central tendency and dispersion, using mean, mode and median. A total of 385 participants were randomly selected to give their views about whether or not the future profits at Home Depot are influenced by interest rates and sales. The standard deviation for interest rates: 7.836266 was less than the mean: 9.695538 suggesting that they fall towards the mean (table 2). It also means that the statistical test…
