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…

3.1 Matching day data For testing the two hypotheses of this research the methodology used is qualitative research. For understanding the personality traits and quantitative research for conducting statistical regression in STATA and the usage of questionnaires. The data consists of questionnaires, mathematics and microeconomics grades that were collected from the freshmen students studying the bachelor program, Economics and Business Economics at the Utrecht University, provided by the school.…

within a 95% confidence interval. If the p-value is smaller or equal to the variable, then reject your null hypothesis in favor of your alternative hypothesis. If the p-value is greater than the variable, then don’t reject null hypothesis. A chi square (X2) value is a tool to help determine whether distributions of categorical variables differ from each other. The categorical variable yield data in the categorical form. The numerical variables yield data in numerical form. Lastly, the degrees of…

respectively, while the non beekeepers 10.5% and 89.5% of them got the extension service monthly and yearly, respectively. From this result most of the non beekeepers concerning the frequency of contact with extension service was yearly. As a result, x2-test calculated as a significant differences (p=0.00 in extension service among beekeepers and non beekeepers (Table 4). From the total sampled beekeepers 82% of improved and traditional beehives owners got extension service similarly. The…

2.5. Statistical analysis Multivariate analysis was performed using two algorithms: PCA and 2-D HCA heat map. The PCA, based on the correlation matrix, was performed using XLStat-Pro 2015 software. The 2-D HCA heat map was carried out with the ArrayTrack, and the Ward's minimum-variance method was used for runs and hydrocarbons clustering. A probability level of p=0.05 was considered as significant difference. The data obtained from the RSM on the hydrocarbon removal were subjected to the…

Abstract Objectives: The anticonvulsant effect of cannabinoid compound illustrated in various models of seizure and epilepsy. On the other hand, there are controversial findings about the role of large conductance calcium-activated potassium (BK) channels in the pathogenesis of epilepsy. Also, there is no data regarding the effect of co-administration of cannabinoid type 1 (CB1) receptor agonists and BK channels antagonists in the acute models of seizure in mice. In this study, the effects of…

Therein, force-free refers to…

Math IA Internal Assessment Men’s Height and High Jump Introduction: The high jump is a track and field event in which competitors must jump unaided over a horizontal bar placed at measured heights without dislodging it. High Jump is an event which used to be famous in early years and now it has reached some great heights in Commonwealth Games. In Today’s world High Jump has been introduced in a-lot of schools and there is a-lot of competitions which are held every year. I personally chose…

The optimized PF0 encapsulated hybrid NCs formulation was achieved by a two-step process (Fig 1) using nanoprecipitation and subsequently coating with chitosan. In Step-I, the nanoprecipitation technique was used to prepare PF0 loaded BSA NCs (PF0-ANC). In this nanoprecipitation technique, acetone was used as a desolvent [40]. Varying concentrations of PF0 solutions (125µM - 375µM) and BSA solution (156.25µM – 468.75µM) (Table 1) were mixed in a glass vial. The PF0 BSA solution was then added…
