selection, required training, and performance evaluation scores are also required. T-test A t-test is used to evaluate the differences in means between two groups, which can be either independent or dependent (StatSoft, Inc., 2011, para. 1). The dependant variable is affected by the independent or predictor variable. Levels of measurement using a t-test include numeric, consisting of numbers as values and nominal, consisting of numbers assigned to names, categories, groups, or levels (Hopkins, 2000

What is forecasting? Forecasting is the art and science of predicting future events. As a science it uses historical data and projects them into the future using mathematical models. As an art it uses intuition or judgment to predict the future

translating past experience into estimates of the future. Forecasting is the process of making statements about events whose actual outcomes (typically) have not yet been observed. A commonplace example might be estimation of the expected value for some variable of interest at some specified future date. Prediction is a similar, but more general term. Both might refer to formal statistical methods employing time series, cross-sectional or longitudinal data, or alternatively to less formal judgemental methods

related variable is the EF a domain that controls the inhibitory responses that influence the behavior inhibition and inhibitory control. The study fails to prove a substantial reason to support the correlation existing between inhibitory control and fluency, planning, working memory and set shifting. This works especially in the salient to the development of the problem-solving skills required for active functioning. Independent variables can be called trial or indicator variables. Variables can

states and eight possible contributing factors such as per capita income, high school dropout rate, average precipitation, population density, and urbanization. Our analysis revealed that of the eight possible contributing factors, only three variables (namely, urbanization rate, high school dropout rate, and population density) affected property crime rates. Our data analysis model accounted for approximately 66% of the factors contributing to property crimes. The model is generally considered

scores on the dependent variable are adjusted to take into account (control) a covariate(s). For example, differences between conditions of an experiment at pre-test can be controlled for. Analysis of variance (ANOVA): An extensive group of tests of significance which compare means on a dependent variable. There may be one or more independent (grouping) variables or factors. ANOVA is essential in the analysis of most laboratory experiments. Association: A relationship between two variables. Bar chart:
