Pearson's chi-square test

3.4. Principle Component Analysis (PCA) Principle component analysis, also referred to as eigenvector transformation, Hotelling transformation and Karhunen Loeve transformation in remote sensing, is a multivariate technique [66] that is used to decrease dataset dimensionality. In this technique, the original remote sensing dataset, which is a correlated variable, is distorted into a simpler dataset for analysis. This permits the dataset to be uncorrelated variables representing the most significant

participate in the study, and only one declined to participate. The nurses in each PHCC were contacted by telephone and received verbal and written information about the study. The data was analyzed using statistical software, STATA, and Pearson’s chi-square test was used to test the statistical significance of the findings. Questionnaires were distributed to 277 nurses and the response rate was 69.3%. Critical Analysis Eva M Sundborg, Nouha Saleh-Stattin, Per Wändell and Lena Törnkvist were the authors

behaviors. Those with missing values or “not applicable” responses were excluded from the relevant analyses. In order to assess the degree to which STI was associated with multiple demographic, sexual and behavioural variables, Pearson’s correlation coefficients were calculated. Chi-square analyses were conducted during

A researcher must think about the data collection and sample size in the early stages of the research process because it will affect the way the researcher analyzes the data. There are two main reasons a researcher should do it in the early stages. The first one is that the researcher cannot apply just any technique to any variable. The other one is the size and nature of your sample are likely to impose limitations on the kinds of techniques you can use (Bryman 2008). The female researcher wants

(ANES), which included adults that were sampled across the nation. Their responses to the questions were randomly chosen. Multiple analyses were ran on the categorical demographics given: race, political party and gender. We are running all of these tests below to find out if symbolic racism and fondness of Obama are related. There were 191 females and 159 males, for a total of 350 participants. Subjects were represented by 40.9% Democratic party, 20.6 Republican Party and 31.1% Independent party. The

The field of statistics is a standout amongst the most ordinarily utilized numerical fields as a part of ordinary life and is available in games, media, and business organizations. The world depends on insights to assemble essential data and to precisely anticipate data for different imperative purposes. Nonetheless, the field of statistics is not as ancient as society may think it to be. It was initiated in the mid Twentieth Century with the establishing of the primary statistics departments on
