Which score has the highest relative position: a score of 47.4 on a test for which X = 42 and S = 9, a score of 5.6 on a test for which X = 3.9 and S = 1.2, or a score of 386.8 on a test for which X = 358 and S = 48. Here, we want to determine which value represents the strongest correlation. Explanation: According to the rule of correlation coefficients, the strongest correlation is considered when the value is closest to +1 (positive correlation) or -1 (negative correlation). A positive correlation means that if one variable gets bigger, the other variable tends to get bigger. Creating a scatterplot is a good idea for two more reasons: (1) A scatterplot allows you to identify outliers that are impacting the correlation. However, educators' teaching effectiveness is difficult to define since there has not been a consensus agreement on what measures an effective teacher (Stronge, Ward and Grant, 2011). The strength that exists amongst the interrelation of two variables is measured with the help of correlation. Explain your reasoning. -0.5 b. -.40 vs -.80 b. The sign (+ or -) represents the direction, while the numerical value represents the strength of the relationship between the two variables.
