Does the high possibility of forgetting issues about statistics very easily make people to think they hate statistics?
I am one of them who study and while studying statistics understood issues about it almost clearly, but after one week as if I never learn them. I then have to start from the beginning.
Possibly, but it is more likely something else.
If you view statistics in its superficial aspect: The numbers, the formulas, the fancy words, and the rules, you will really be confused and will be prone to detest statistics altogether.
What I tell my students is to view statistics as adjectives that describe clearly the real color, shape, amount, and value of things.
Whenever you learn a new concept in statistics, instead of writing down what it is, make an association of what it is used for. For example, with the term "variable", write down a word such as "opposites", or "ying/yang", or "red vs blue". For the word "limitations" you can write down the words "don't go there", or "#failtogetaninvitation", or "rejected".
Make yourself a nice chart with pictures of these describing words net to the actual term, laminate it (there are cheap mini laminating machines for sale even at pharmacies) and keep the chart with you. Once you maneuver those concepts I PROMISE you that you will enjoy applying statistics to your research, and you may even become partial to quantitative rather than qualitative analysis in future research studies. After all, it is through quantitative research that we are able to truly assess what would make something produce more in a shorter period of time. Try this method and let us know how it worked!
