What is the symbol for correlation coefficient?
The symbol for the correlation coefficient is typically denoted as "r" when referring to Pearson's correlation coefficient. This statistic measures the strength and direction of the linear relationship between two variables. In the context of other correlation methods, such as Spearman's rank correlation, the symbol "ρ" (rho) is often used.
What serves as standard of comparison to evaluate effect of the independent variable on dependent variable?
The correlation coefficient, plus graphical methods to verify the validity of a linear relationship (which is what the correlation coefficient measures), and the appropriate tests of the statisitical significance of the correlation coefficient.
What distinguishes the correlation method from experimental?
The correlation method examines the relationship between two or more variables to determine if they move together, without implying a cause-and-effect relationship. In contrast, experimental methods involve the manipulation of one variable to observe its effect on another, allowing researchers to establish causality. While correlation can reveal patterns or associations, only experiments can determine whether changes in one variable directly lead to changes in another. Thus, the key distinction lies in the ability of experimental methods to infer causation, which correlation methods cannot provide.
Compare and contrast the methods of software project estimating known as size-related estimates and function related estimates?

Is correlation resistant to outliers?
No, correlation is not resistant to outliers. Outliers can significantly skew the results of correlation calculations, leading to misleading interpretations of the relationship between variables. For example, a single extreme value can inflate or deflate the correlation coefficient, making it appear stronger or weaker than it truly is. To assess relationships more robustly, alternative methods like robust correlation coefficients may be used.
What methods are used in estimating animal populations apart from quadrats?

What are the different methods of estimating working capital requirement of a firm?
There are two main methods of estimating working capital within a firm. These include the conventional method which measures cash flow, and the concept of operating cycle.

How can you estimate the value of an irrational number?
There are different methods for estimating irrational numbers. For numbers like pi or e, there are infinite series which can be used to calculate their value to the required degree of accuracy. There are numerical methods - such as the Newton-Raphson iteration - for estimating roots of numbers.

This method of cost estimating is quick but subjective and not as precise as other cost estimating methods. Technical and cost data from similar systems exist.?
The method of cost estimating described is likely the analogous cost estimating technique, which relies on historical data from similar projects or systems to provide a quick estimate. While it can be efficient, its subjective nature and reliance on past data can lead to inaccuracies, especially if the previous projects differ significantly from the current one. For more precise estimates, methods like parametric or bottom-up estimating may be preferred, as they rely on detailed analysis and data.
Can a correlation be measured?
Yes, correlations can be measured using statistical methods such as Pearson's correlation coefficient or Spearman's rank correlation coefficient. These measures quantify the strength and direction of the relationship between two variables.
