There may be a couple of statistic questions in the examination. Kaya it’ll pay to brush up on these simple concepts-the mean, mode, median, and range.
So, how do you solve for them? Here’s how:
- Mean = Average. All you have to do is to add all of the scores and divide it by the number of scores. For example: 3, 4, and 5 will give you a mean of 4 because (3+4+5) divided by 3 is 4.
- Mode = The score with the most repetitions. In short, yung pinakasikat or uso. For example: 3, 4, 4, and 5 will have a mode of 4 because there are 2 4s and just one each of 3 and 5.
- Median = Middle. Write all of the scores in ascending order and pick the number in the middle spot. For example: 3, 4, 5, will give you a median of 4 because it is the middle number.
- Range = The largest score minus the smallest score. For example: 3, 4, and 5 will have a range of 2 because 5 – 3 is 2.
It’s time to put that into practice. Here are a couple of worksheets to get you started.
