playing with SPSS

I am not good in statistics. But I have to master SPSS and Structural Equation Modeling to figure out what is hidden inside my data. It is fun to play with the data. There are a lot of things can be interpreted by using SPSS but I realized that we in Malaysia don't have a good reference for a person who want to use SPSS and learn statistics in one time. But of course we can buy a lot of statistical and SPSS books in English and I suggest a book from Andy Field. He described the usage of SPSS and statistic in easy way and sometime include funny stories to make it less bored.
Below are some of my data displayed in bar chart from crosstabulation , I wish I could put a bigger ones to show the speed desire in different areas. The risk compensation theory seems to be occured but I need to analyze it more. ^^

it's time to play with numbers n words

ML is one of my task.


Ok. Now it’s time to analyze the data. For the first part I will do some descriptive analysis to investigate deeply who are my respondents and what actually their perspectives towards safety. Which one is fits to our community’s level of probability – uncertainty or risk? It is quite interesting for me to figure out. If our motorcyclists know that they are exposed to the traffic accident each time they ride the motorcycle, it means they are willing to take a risk by doing the risky behaviors such as speeding and not wearing the helmet, but if they don’t have the clue and blur about the danger – they are playing with the uncertainty.

Previous research by Pang et al claimed that 75% of motorcycle’s accidents involved with other road users and about 25% more involving the road-side objects. I would like to compare this report with my study. One of my friends is doing his PhD also in motorcyclists with Intelligent Transport System (ITS) as the objective to improve their safety. This is a very good research while I have another girlfriend doing her PhD focusing ITS in Germany.

My task is quite different because I try to see more into psychological, cognitive impact and also more into risk management and communication. When the ITS tools are ready to be used in Malaysia, motorcyclists need to be told on how to use it in a correct way. That is my job to find out how and when to inform them about how-to-use and when-to-use the tools. If not, the tools will be a gajah putih like Smart Tag or Touch n go , because our people don’t know what the system can do for them.( And become more helpless when sometimes the electronic toll collector’s company can’t manage their things in a good way.)

Malaysian is busy talking about the PPSMI. Well, I don’t want to comment more than I should, just read this entry from
