Randomization in an experiment reduces bias between the treatment and control groups?
True
What is the type of homeostatic mechanism that reduces any changes in the value of a variable or keeps a variable close to a particular pre-established setpoint?
Such a mechanism is called a negative feedback.
Does increasing the variable cost increase the contribution margin?
Increase in variable cost reduces the contribution margin as following formula suggests”Contribution margin = Sales revenue – Variable Cost
What is a positive negative correlation?
Correlation determines relationship between two variables. For example changes in one variable influence another variable, we can say that there is a correlation between the two variables. For example, we can say that there exists a correlation between the number of hours spent on reading and preparation and the scores obtained in the examination. One can infer that higher the amount of time spent on preparation may result in better performance in examination leading to higher scores. Hence the above is a case of positive correlation. If an increase in independent variable leads to an increase in dependent variable, it is a case of positive correlation. On the other hand if an increase in independent variable leads to a reduction in dependent variable, it is a case of negative correlation. An example for negative correlation could be the relationship between the age advancement and resistance to diseases. As age advances, resistance to disease reduces.
What reduces a equation that has two variables to an equation that has one variable?
combining like terms or subtracting from both sides of the equation.
How does sample size affect validity of results in a research?
A large sample reduces the variability of the estimate. The extent to which variability is reduced depends on the quality of the sample, what variable is being estimated and the underlying distribution for that variable.
