## Why is Statistics So Scary?

on Sep26 2007I have been completely immersed in the world of statistics for the last three and a half years. I have had the privaledge of teaching for most of that time as well. What I am amazed to see over and over again is that there are hundreds of people out there who are afraid of statistics and don’t know why!

My first question when someone says, “I hate statistics,” is always, “Why?”

The most common answers I get are:

“I am really bad at math.”

“My friend said it was hard, and I have to take it.”

“I hated that class.”

My response to the first one is that statistics uses some basic math but really its the art of understanding information.

To the second I usually say nothing because no one can get through college on what other people do in their classes.

The third is the one that interests me the most because usually a bad instructor was to blame. I don’t ever want to be one of those. Now, you have to know that the reason that I ask why is because as an eductator I want to know things that I can do to improve my students’ experience with statistics.

What I need is the nitty gritty. Why didn’t/don’t you like your statistics class? Is it because the examples didn’t apply to you? Is it because the instructor couldn’t answer your questions? Is it because it was all words and not enough graphics? Is it because you had a bad attitude going into it so the class never stood a chance in your mind? I am looking for people’s specific comments on the question, “Why is statistics so scary?”

You raise an interesting question. I have responded in my Oct-17-2007 posting, ” Statistics: Why Do So Many Hate It?” (http://abbottanalytics.blogspot.com/2007/10/statistics-why-do-so-many-hate-it.html) on the Web log I co-author with Dean Abbot, “Data Mining and Predictive Analytics” (http://abbottanalytics.blogspot.com/).

I think Stats can be scary for some students is because all the greek letters and profs not making connection to real life examples.

“I hate statistics”.

I hate they way statistics is taught. It is too broad of a topic for a specific course, and should rather be integrated (no pun intended) with other courses. For example, while learning integration in a calculus course, there could be a small aside involving the normal distribution (since the normal dist. integrated from -inf to inf equals 1). One of the few parts of statistics that I don’t see able to be merged into another course is probability, which could easily be fit into a ~3 month course.

I also dislike the inconsistent notation used with statistics. It’s like everything BUT statistics uses a nice, standard notation.

One last complaint; I absolutely HATE the reliance on numbers (this ties into the way it is taught). There is so much that could be done symbolically, but is instead done using brute-force methods such as using random numbers.

Hopefully I can avoid any more statistics courses until I’m done with my schooling ðŸ˜‰

I’ve been relearning statistics lately. I’m not a mathematician, but i generally enjoy math and i use it often in my job. I find statistics slightly intimidating because it’s difficult sometimes to figure out if you have the right answer (we’re talking about a field that’s defined two different ways to be wrong). Even if you apply the methods correctly, you can get bad answers if you assume an incorrect model for your data; and often you don’t arrive at a firm answer, but rather some confidence interval or likelihood.

Finally, i think that statistics as an academic domain is confused with statistics as a tool of persuasion (in the sense of “lies, damned lies, and statistics”). I think this has given the layman the impression that statistics is not so much a rigorous branch of mathematics, but rather a means of selecting the best data to support your own view.

I agree with you when you say statistics is used as a “as a tool of persuasion.” The misuses of statistics in our daily lives are unbelievable. I have my students bring in an example of an unfounded statistic for a take-home assignment. They never seem to have any problem finding one and I have never had a repeat. They bring me things from the radio, television, and all kinds of print. It is amazing to me.

I think I have a hard time with statistics simply because of what such a study implies. In my mind, it’s all about how to manipulate the masses and how to control large populations. In that respect, it’s no different from learning how to fight in a war, how to shoot a weapon, how to do all of the things that really seem to run contrary to who I really am, individually, at my core.

To most people, I’m an outlier just because I think this way. I might prove problematic to someone who needs to do some serious manipulation. In that case, I would simply be done away with. All one would have to do is to exclude me from the data. You see what I’m getting at? It can be dehumanizing. Some people get left out of the sampling process. Then their needs go unmet in favor of the so called average. It could happen to anyone, really. Read Jung’s work, The Undiscovered Self, (if you haven’t already) and you’ll know what I’m getting at, and why I personally am so wary of statistics.

I know that statistics can be useful, but the problem is that it’s such a handy tool that like some new invention, it can be put to good use, or it can cause such widespread destruction. What’s at stake here is the human soul.

What makes it worse is the entire educational system having to rely so much on the directive approach to educating, rather than non-directive, as though individuals can’t think for themselves, but need to be controlled and manipulated and kept from straying like some seemingly insignificant outlier.

Statistics is difficult not because people can’t think abstractly or can’t do algebra, but because of what it implies and the way it gets administered, and the way it takes your soul away, and the way it forces you to play the game. Nevertheless, I am learning it because I have to. I might live or I might die in the process. War is hell.

I hated statistics during my undergraduate years mainly because it was taught by a bad instructor. I don’t want to blame my mishaps on others but I found the subject difficult to understand and follow.

When I reached graduate school I took a couple of classes that was taught by a different instructor and it was as though cold water had been splashed over me! The new instructor I had taught the subject in such a different manner that it made things easy to comprehend and follow.

I quickly realised that the problem my first instructor had was that she focused way too much on the theoretical side of statistics (in a monotonous manner) and failed to teach using more pragmatic methods.

For example, instead of focusing on explaning multiple regression in terms of equations and the relationships between X, Y Z and nothing else and then bring up some stats output and proceed to explain it without showing us how the output came about. We would then attend fortnightly tutorials AFTER the lectures and try to run the output ourselves.

On the other hand, the postgrad instructor I had would explain it quickly in a theoretical manner, then reiterate using a real life example and THEN best of all fire up a stats program such as SPSS on the spot and show us how to crunch the numbers, generate the output and interpret it. The best part is when you can relate the output/outcome back to the theory to see how it all falls into place!

Because statistics follows logic – if one part is poorly taught earlier on, I tend to find that many students (such as myself) will have difficulty understanding many concepts later on.

I hated statistics because my instructors focused so much on the mechanics of the tools – the histograms, the distributions etc. that I never got why I was learning all of it.

We never ever applied the data to a practical real-world problem. We never understood what sort of conclusions could be made, and what couldn’t. We were just given random data sets and told to compute variances and means… and I was like, why bother?

Trust me. I went through Stats Honours. I came away with a lot of formulas, but I still don’t know when to use which statistical tool. My friends who use stats on the job tell me that you only learn by doing statistical analysis with a mentor who’s really good at both stats & real world analysis.

In essence, I wish my college instructors had focused on the whole learning process. Explain the objective (central tendency). Give examples of real world situations where that objective is useful (average weight to fight obesity). Go into maths of tool (mean, median etc.). Compare and contrast strengths and weaknesses of tool with respect to that real world example. Case study – full analysis homework with conclusions & interpretations also assessed. Now that would have been a great stats course.
