From the table, we observe the coefficient for the is 0.36488; this implies that for any unit change in we would expect the dependent variable to increase by 0.36488. The coefficient for the explanatory variable is significant at 5% significance level. We can
This paper assesses the role of various variables in entrance. The variables considered include academic level, age group, marital status, and employment status.
Age is a major determinant factor in lots of case and this is no exception in this research. The

R2 measures the proportion of the variation on the dependent variable which is explained by the independent variable in a linear regression model. It also measures how best the regression model fits. Adjusted R2 adjusts the statistics based on

Estimation of the sample size starts from table I, where the general level two is matched with category of the batch size where 40,000 units falls, to get N as the code letter. From Table II-A, code N is equivalent to 500, which
During analysis, a group variable is created to accommodate the two groups whose means are being analyzed.
Based on the Levenes Test for Equality of Variances, which puts the level of significance (p-value) at 0.229, we use the equal variance
Existence of diversified literature on subjects offers contradictory information that that may confuse researchers’ development of hypothesis through determination of dependent variables. An example of the source of the
The conclusion made by the work is that the firefighter needs to be given proper training to avoid fatalities and professional trainers need to be employed to educate the firefighters in a scientific manner.
It is an attempt to describe the movements in a variable with regards to movement in other variables. Linear regression is a form of regression which attempts to build a linear model between dependent and independent variables. In a linear equation, generally represents the intercept of the equation while represents the slope of the equation.
The use of statistics in reporting research, survey and business findings has often received criticism. This is mainly when there is misuse of the data so that facts are misrepresented and only some part of the observed
Alternatively defined, a statistic is a sample characteristic.
There are basically two types of statistics; inferential and descriptive (Anderson, Sweeney & Williams, 1994). While inferential statistics involves the description of the population based on the results drawn
Stratified sampling – the population in this case is divided into groups in a way in which the members of each group have similar characteristics. This is called stratification and the groups are referred to as strata. Random samples
The mode, for example, is suitable for describing data on a nominal scale while for ordinal data; either the mode or the median should be used. The mean is however more suitable for variables on a ratio or interval scale (Hanna and

In this project an attempt has been made to forecast milk production using statistical time series modeling techniques – double exponential smoothing and Autoregressive integrated moving average models. Forecasting of milk production enables policy makers and planners to estimate the supply of milk requirement in the future.
2. The histogram is skewed to the right. This is because its right tail is longer than its left tail. This is also due to the reason that the tail on the right is more positive than the tail on the left. Furthermore this is also due to the fact that values with higher
The author states that the first step in any t-test analysis is setting both the null and alternative hypotheses so that it can be determined whether there is any difference in the two means under study. In this case, our main interest is to know whether there is a difference between the oxygenation levels of the two groups.
This mainly took the form of in-depth interviews, which were administered in sets of 25 for each city in the Budapest Metropolitan Region (130). Leaders and firm managers were the main respondents of the interviews in order to explain their decisions
The slope of the graph is 0.39 and the y-intercept is 43.714. The equation of the graph is as follows, Y=43.715+0.39x. R and R squared. From excel, the values for R and R squared are 0.678 and o.46 respectively. Interpretation of the findings. From the graph, the coordinates are evenly distributed across the line of fit.
This is known as a spurious regression since it implies dependence although the variables are independent of one another. The problem will go away if the regression is run in first differences, or a lagged value of Y is
Accurate diagnoses and treatment is the very mainstay of patient-centered medical care (Broyles, 2010).
Likewise, the use of statistics one finds the way in which the use of interval variables may help the Federal Qualified Healthcare Center to promote
Hence mean (average) is the appropriate measure for measuring the central tendency. The average salary of the corporate customers is $300,000.
The frequency graph with addition of new salary points of $500,000 and $600,000 will affect the skewness of the
The author states that in 2011, the Pearson correlation is zero meaning that the two variables, that is, borrowings and tax revenues are not correlated or they do not cause each other. In 2012, the Pearson correlation is 0.009853 meaning that there is some correlation between taxation and borrowing but it is very weak.
