Smoking severity. The questions about number of cigarettes a day and time to first cigarette (included in Studies 1 and 2) were supplemented with the remaining items of the Fagerström Test for Nicotine Dependence (Heatherton et al., 1991). Unreported measures. The main study included the 6-item gain discounting measure used in the Pilot Study. The original test (Du et al., 2002) includes 6 items for 7 different delays and 2 different reward magnitudes, whereas the present version only asked 6…

According to the results, the mean amplitude of normal reflex is greater than the Jendrassik maneuver. There should be greater amplitude with the Jendrassik maneuver because Jendrassik maneuver reduces the person’s ability to voluntarily affect the response to the tap made to the tendon even if they are fully aware of why the distraction is being incorporated into the test (Zabelis et al. 1998).The Jendrassik maneuver had low mean amplitude of the angle of deflection which can be due to some…

There was no significant correlation found between the Numeric and Spatial conditions, indicating there was no relationship between these two conditions. This means we need to accept the null hypothesis that there is no interaction between these two sets of conditions. It should be noted that even if we adopted a two-tail hypothesis, that the result would still be insignificant, however not by large degree (P=0.104). Previous research made a one directional hypothesis seem more appropriate, due…

Significant figures are the numbers that are important when performing calculations in chemistry and other fields of science. These numbers are important to scientists because they determine the accuracy and precision to which their measurements and calculations were made. Significant figures are important to the scientific method because the results of experiments that are performed to test hypotheses can be altered due to mistakes of significant figures. Measurements are only as accurate as…

However since we have the four variables and that we’re measuring first year average scores. The formula should look like this: First year average score (%) = β0 + β1non-academic member + β2satis first-year + β3math-center + u Since first year average score is a percentage variable, it is often used in the level form as a result. So models with level-level or level-log will work best with this average score for estimating. However since we are measuring with more than two variables,…

This portion of the study discussed the estimated results of each of the specifications. The objective is to have a clear understanding of the determinants of infant mortality. Stationarity Check: Regression of a non-stationary time-series variable may cause a spurious regression or non-sense regression (a symptom of spurious regression is that the R-square value is greater that Durbin-Watson test statistics) which is not desirable. After estimating the first regression, the R-square value is…

Soil preference of the Red Compost Worms, Eisenia fetida INTRODUCTION Earthworms provide countless benefits to humans, plants and animals, by improving drainage, advancing nutrient accessibility, and providing a steady soil system, helping to develop farm production. They benefit the soil ecosystem by decomposing and recycling organic matter, opening up pores inside the soil to develop its formation and supplying food for predators . By adding nutrients to the soil they inhabit, earthworms are…

Clearly, randomization is crucial to eliminate certain bias and have an accurate trial. 6. Explain how the intervention(s) in the treatment arm differed from how participants in the control arm were treated. In other words, what is the trial testing? Participants in the treatment arm were given 12.5 milligram Zinc Sulfate, whereas the participants in the control arm were given a placebo. The trial is testing whether Zinc Sulfate is beneficial to children who have Malaria or not. 7. Was the…

measures of associations refers to the statistical strength of the relationship between the variables of interest. This can be described in numerous ways; this also depends on the analysis. This is concerned with how each variable is related to other similar variables. This association is based on the strength of the linear relationship in the degree of monotonicity. To the degree that it is based on counting various pairs in a relationship. Known as a statistical tool that investigates…
