R square amounts to 0,155 and indicates that predictive power of the model is 15,5%. Model`s strength is poor, but adjusted R square is lower than R square, so there is no need for introduction of other factors to explain the changes in dependent variable. Durbin Watson statistic is 1,983, which is close to value of 2 and indicates that there is no autocorrelation. Table5: Model summary – Irrational predictors Model R R Square Adjusted R Square…

The experiment consisted of numerous limitations and uncontrolled variables which impacted on the validity of the outcome. The lack of repetition was a major limitation in this experiment. The shortage of repetition forbids the elimination of outliers that may cause inaccuracy in the practical outcome. The lack of repetition in this experiment provided erroneous practical results where experimenters are mislead due to outliers, hence conclusions could not be accurately drawn. According to…

indicating that initiating structure has little influence over job satisfaction. As according to Hair et al. (2006), the bigger the Beta value, the higher the influential factor by the particular independent variable. However, in this relationship, the influence power of independent variable is apparently low. Moreover, the relationship also deem insignificant because the significance level is at 0.3, which is above .05. H2: There…

statistic is useful in comparing things. In our book Naked Statistics by Charles Wheelan we read some chapters in where we use stats in three different ways to get close to the answer without using all the data. We see how indepednt variables and dependent variables relate to each other and how we can get close to seeing how close they relate without using the full data. Correlation is a form of statistics in where it shows us how two things are related to each other. In our book they use the…

have chosen two variables that are individually described as the explanatory (or predictor) variable and response (or outcome) variable. A variable that can be used to explain, or can be said to cause differences in another variable is called an explanatory variable. The variable in which the differences are observed is called the response variable. I am interested in the relationship between writing (describe) and the spelling. Because of these choices, my response (outcome) variable will be…

* Used for prediction and explanation * Variables selected based on theory * Should be able to group the variables into independent and dependant * Non-metric IV’s can be converted to Metric IV’s Step 1 – Significance testing * Involves testing the significance of the overall regression equation as well as testing the…

three important assumptions to test before the analysis starts. First of all, regression assumes that variables have normal distributions. Although most of variables show distributions close to normal, the small amount of variable that shows abnormal distributions is analyzed by the another statistical method. Moreover, assumption of a linear relationship between the independent and dependent variables is necessary because standard multiple regression can only accurately estimate the linear…

services, education, arts and culture, and health, which can not represent the whole population of nonprofit organizations. I believe that the author try to establish the validity and reliability of the measurements by adding some of the control variables to control the measurements. However, I still believe that the measurements are unreliable, because of the sampling error. 4) Are any hypotheses stated? Are these hypotheses justified in terms of theory or previous…

studies, investigation is nonetheless of the key concept that is being used to analyze. When dealing with a particular topic that requires investigation, the scientist needs to take into consideration all variables. In other words scientific investigation is basically the way scientists test all variables and concepts to obtain an explanation for the desired concept. Scientific method is the procedures that a scientists will use when conducting an experiment/investigation. “Scientific…

manipulated variables explained throughout the experiment. The two main things used in this experiment will be the solute and the solvent, which is Alka Seltzer and water. In the duration of this paper I will be describing the various aspects of what solutes and solvents are, and how there will be used during…
