# Psy 315 Week 2 Team Assignment

Week 2 Practice Worksheet psy315 WEEK 2Provide a response to the following questions.1.The Wilcox & Keselman (2003) article from this week’s electronic readings discusses two problems with measures of central tendency: skewness of the data and outliers. Discuss each of these issues and how they affect measures of central tendency. This question is basically about how outliers and skewness affect data analysis Outliers : Outliers are points in the dataset which are values that do notadhere to the average behavior of the data points. They might effect the calculations of Mean a...measure of central tendency is a single value that attempts to describe a set of data byidentifying the central position within that set of data. Skewness is a measure of the asymmetry ofthe probability distribution of a real-valued random variable about its mean. Outlier is anobservation point that is distant from other observations. The median is less affected by outliersand skewed data than the mean, and is usually the preferred measure of central tendency whenthe distribution is not symmetrical. As the mean includes every value in the distribution the meanis influenced by outliers and skewed distributions.When a distribution is skewed the moderemains the most commonly occurring value, the median remains the A measure of central tendency is a single value that attempts to describe a set of data byidentifying the central position within that set of data.
