eliminated‚ that is‚ . This statistic ranges from -1 to +1. Absolute values above 0.2 indicate great skewness (Hildebrand‚ 1986). Skewness has also been defined with respect to the third moment about the mean: ‚ which is simply the expected value of the distribution of cubed z scores. Skewness measured in this way is sometimes referred to as “Fisher’s skewness.” When the deviations from the mean are greater in one direction than in the other direction‚ this statistic will deviate from zero in

plan describes how to use sample data to evaluate the null hypothesis. The evaluation often focuses around a single test statistic. Analyze sample data. Find the value of the test statistic (mean score‚ proportion‚ t-score‚ z-score‚ etc.) described in the analysis plan. Interpret results. Apply the decision rule described in the analysis plan. If the value of the test statistic is unlikely‚ based on the null hypothesis‚ reject the null hypothesis. Decision Errors Two types of errors can result

ASSIGNMENT: Ethics in Statistics There are a number of possible ways in which unethical behavior can arise in statistics and researchers should steer clear of these. It is relatively simple to manipulate and hide data‚ projecting only what one desires and not what the numbers actually speak‚ thus giving birth to the famous phrase “Lies‚ damned lies and statistics”.
