  • Exercise for Your Brain

    I want to make a distinction between reviewing lecture slides and actually learning. Anyone can review lecture slides and gather information. It’s really a memory game to review slides and remember facts. There is no guess work involved with attending lecture. The speaker of the house gets up and recites facts and reflections for his…

  • Statistics Books

    So if you pay attention to my posts on facebook or any other social media- I write books on statistics. And my books are fairly short in page numbers because I believe in the saying ‘get to the point’. No one – and I mean no one has time. You have families and responsibilities outside…

  • Look it up

    My father once bought us the entire set of encyclopedia britannica. The books were suppose to serve as our information source. Our world wide web had not been invented as of yet. (Am I dating myself right now? Probably so lol) In any case, if we had a question about our school work, the world…

  • It’s not Random so Can’t do it

    Hello people! I have not written a blog in a good minute.  I was inspired this morning to write about the steps leading up to analysis. So I have consulted quite a few students up to this point. And I made the observation that some research questions are formulated without considering how to collect the…

  • Two Sample T versus Paired

    I may have mentioned this topic in the past- two sample dependent T test versus paired T test. This is not a shaming session. But people think they can take a paired -t test structure and perform a two sample mean comparison. It’s not translatable for several reasons. One of the assumptions of a two-sample…

  • Career Boost

    Dear All, As an undergraduate student at Rutgers, I had no idea how to acquire marketable skills for the outside world. Technically, college is part of the outside world but it’s really not OUT-side. It’s more of a parallel universe. You are not in the workforce YET.  That is why I have dedicated some of…

  • Mosaic Graphs

    Mosaic Graphs

    Chi-square tests for categorical data will reveal if there is an association between the variables in your contingency table. However, the test statistic will not tell you where dependencies exist within the cells of your table. People typically illustrate count data with bar charts, pie charts, and histograms. And those illustrations are great for a…

  • Kendall Tau

    The phrase Kendall Tau is not typically introduced in your basic statistics class. But if you were performing a correlation for your  dissertation defense- make sure you don’t need one. As a matter a fact, do me a favor…If you are working with a correlation right now…Classify the variables in your correlation as one of…

  • Tee Shirt Special

    My company tee shirt is in the shop on my site. It contains a butterfly symbol which I personally chose because it is a reminder of my late father Gary Moore. My Dad was not a mathematician, instead he practice law. What is the connection to butterflies? One day I was talking to my Dad…
