Correlation Paper Essay

CorrelationCorrelations measure the family relationship between both variables. Establishing correlations allows seekers to make predictions that add the knowledge base. Different rules that establish correlations argon employ in different situations. each rule has advantages and disadvantages that provide researchers info that is apply to understand, rank, and visually dilate how variables are related. The Pearsons, Spearman, Kendall Rank, and autocratic and negative correlation are method actings utilize to establish a correlation between variables. The Pearson method is a simple elongated correlation used or illustrate how strong of a relationship both variables have. The Spearman method ranks data by station or fig and is often used be nonplus the equation is simpler than Pearsons. The Kendall Rank method measures the personnel of dependency between two sets of random variables. Depending on the use of the information result stipulate the best method for the r esearch suggest. individually method has advantages and disadvantages. The research project and individual researcher weigh prohibited the domineering and negatives in order to determine the best method. It is hold that the Pearsons method is easy to understand and illustrates the strength of the correlation. A prominent disadvantage is there fag be astonishment because it may be assumed that correlation establishes causation. The Spearman advantage is it drive out rank order or name data in various ways, depending on the data collected. The disadvantage discussed is there may be a focus on rank and not on the information that creates the rank. The positive and negative correlation method has the advantage that a lot of variables and situations give the gate be used. Variables can be analyse victimization this method that experiments cannot be conducted on. The top disadvantage discussed is that no cause and mental picture relationship can be assumed. other discussed d isadvantage of this method is that it does not story for other variables that may contribute to study variables. Information reveals creating correlations in research using the Pearson method would be reusable in domestic violence because it is a method that is easy to understand. The Spearman method that ranks data was discussed to be useful in the area of ranking of comfort qualities provided by hospice and grade point average or SAT rankings. The Kendal Rank method measures strengths of dependence between two sets of variables like GPA and job performance in the peak field. Discussion about reading progress in children was an example that would utilize the positive and negative method the best.As located correlation determines the relationship between two variables and is used to make predictions in research. Each method has clear advantages and disadvantages, but it is agreed that the easier the method is to understand the more useful it is. One key point that causes c onfusion is the relationship between correlation and causation. It was obstinate that to avoid the error that a cause can be assumed found on a correlation fear must be paid to the specialised method. Not every method is knowing to illustrate cause and affect relationships.ReferencesLing, R. F. (1982). Reviewed run for (s) Correlation and Causation. by David A.
