Statistics AFRAID OF STATISTICS?
FORGOT THE BASICS?
DON'T WORRY WE GOT YOU! GET READY TO LEARN IN A FUN WAY!
Back to Basics
VS Population VS Sample is very confusing to others but let me tell you their difference. POPULATION is the entirety of the subject. An example for POPULATION is all of the high school students in Philippines. Meanwhile, SAMPLE is a portion of the population. An example for SAMPLE is 50 students of high school student in Assumption College San Lorenzo. Population and Sample is easy to understand and I hope you did understand it!!
Back to Basics
Mean, Median and Mode are the words that ever since grade school we've been hearing but do we actually know the difference of the three? MEAN is the arithmetic average of a number set. MEDIAN is the level at the center of a set. Lastly, MODE is the most common level of a number set. It's easy to remember it right?
Back to Basics
One of the basics of Statistics is the Levels of Measurement that's why let's go back to it! The first one is NOMINAL. NOMINAL means that we categorize the data given to us in a specific categories.
Back to Basics
The second is NOMINAL. The meaning of NOMINAL is that once the data are already in a certain category, we start to rank it from their like 1st, 2nd and 3rd.
Back to Basics
For the third one, we have INTERVAL. So what is Interval? INTERVAL describes the distance between each ranking and category.
Back to Basics
Lastly, we have our RATIO. hearing or reading the word 'RATIO' makes you dizzy right? Well don't you worry because RATIO means true zero or there can be no negative numerical value in our data.
Hypo whaaat? Hypothesis Hypothesis whaat? Hypothesis Testing Let's learn about Hypothesis Testing
Hypothesis Testing
Hypothesis testing has two types, Null and Alternative but what is the difference of the two? NULL HYPOTHESIS means all things are equal and there is no difference. Meanwhile ALTERNATIVE HYPOTHESIS means that there is difference between the data.
Hypothesis Testing
Hypothesis testing can occur some errors and there are two types which is FALSE POSITIVE that means you get a good result but it turns out the result is not really good and FALSE NEGATIVE means that you have bad results but the truth is you have good results

Editor's Page Get to know more about the Editor - in - Chief of STATSMAG
I am a 2nd year college student who is pursuing Bs - Psychology as my pre - med course. Someday I want to be a Pediatrician because of my love for kids. My friends call me the 'mother' of the group because I always care for them and help them if there is a chance. My friends also call me workaholic because I never know when to stop doing academics and org works. I can't deny that I'm a workaholic because it is really true. Despite being a workaholic, I still find time to rest and to catch up with my personal life. My love for Kpop makes me sane and makes me happy. Watching Kpop contents or just listening to their music makes me relax. The groups that I do love are EXO, WayV and NCT. So the next time you see me or ask me what makes me happy, I'll only answer you "Kpop" or "Kpop merchs".
