What are the possible reasons for a correlation between two variables?
Chance association, (the relationship is due to chance) or causative association (one variable causes the other).
What is the difference between a variable being tested and a variable being controlled?
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.
Can likert scale be a continuous variable?
As it's commonly used, with each point representing a number, it's not a continuous variable. For example, if someone hits a radio button for disagree=2, then it's a discrete variable. If, however, interval choices between points are allowed by the setting, then the scale is measured and the numbers are assigned as fractions or decimals such as 1.88, it becomes a continuous variable, although still ordinal in nature as one can not infer a set ratio between each response.
What is adjusted odds ratio?
As adjusted odds ratio is defined as "In a multiple logistic regression model where the response variable is the presence or absence of a disease, an odds ratio for a binomial exposure variable is an adjusted odds ratio for the levels of all other risk factors included in a multivariable model." Simply put, it is a measure of association between an exposure and an outcome.
What is the meaning of confounding in statistics?
In statistics. a confounding variable is one that is not under examination but which is correlated with the independent and dependent variable. Any association (correlation) between these two variables is hidden (confounded) by their correlation with the extraneous variable. A simple example: The proportion of black-and-white TV sets in the UK and the greyness of my hair are negatively correlated. But that is not because the TV sets are becoming colour sets and so my hair is loosing colour, nor the other way around. It is simply that both are correlated with the passage of time. Time is the confounding variable in this example.
Can ANOVA test be applied for testing association between independent variable and dependent variable?
Yes.

How is the degree of association between a set of independent variables and a dependent variable measured?
Coefficient of multiple determination
Does Polaris reflect light?
Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)
What is a line that shows the correlation between two data sets called?
There is no line that shows the correlation between two data sets. The correlation is a variable that ranges between -1 and +1.You may be thinking about regression which, although related, is not the same thing.There is no line that shows the correlation between two data sets.

Can a chi square ever tell us whether one variable causes variations in the second variable?
Regrettably, no. The most a chi-square statistic can do is to participate in the measurement of the level of association of the variation between two variables.
What are the similarities between a control and a variable?
There are not any similarities between a control and a variable. However, a Control Variable, is a variable.
What is a correlation variable?
Any variable can be a correlation variable. In some cases there may be no apparent correlation but that, in itself, that means nothing. For example, the x and y coordinates in the equation of a circle (or any symmetric shape) are not correlated. On the other hand, there is a pretty good correlation between my age and the number of cars in the world.A correlation variable is simply a variable that you study to see if changes in the variable that you are interested in is, in any way, related to changes in the correlation variable, and to get some idea of the degree to which they move in line.
What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
What prevails in case of a conflict between memorandum and articles of association?
If there is a conflict between the Articles of Association and Memorandum of Association, the Memorandum of Association prevails.
What apparent contradiction between limited resources and unlimited wants?
