Help - if a graph of my sample data is right skewed, what does that mean? This also tells me that it is not normally distributed, right?
Thanks

The skewed graph means that the sample does not come from a normal distribution. However, you need to run other analyses to be sure as having one graph does not give much information. Analyses such as the stem and leaf, box whiskers...etc would be helpful for you to decide. You can get more info from this site: http://web.uccs.edu/lbecker/SPSS/explore1.htm

For a normal only the population is symetric. A sample can be skewed. You need to plot your data on special graph paper to see how close to normal you sample is. Remember, samples only approximate the assumed population.
