Rank Mode Each group will going to choose what type of hero they want ( Fighter, Assassin, Marks Man, Mage, Tank or Support ) Mechanics: 1. If one of the Team members knows the answer of the question being posted, then he will shout First Blood. 2. In case that the answer of that team is incorrect then it is the chance for the other groups to get the score. All you need to do is to shout Kill Still, the first one I hear will be the one to answer the question. 3. Reviewing If one team got 2 straightlesson corrector Presenting the new lesson C. yesterday’s answer it means Double kill, 3 straight correct answer Triple kill, 4 Straight Correct answer Maniac, and 5 straight correct answer Savage. The questions will post on the front

Who knows this anime character ? “ Ok very good “ So detective conan have some problem in thisexamples/instances message D. decoding Presenting of the new lesson “ 16 – 5 – 18 – 3 – 5 – 14 – 20 – 9 – 12 – 5 18 – 1 – 14 – 11 “ Detective Conan is asking for some help, the one who can help him will surely have a price.

Detective conan

“ Very good “

“P–E–R–C–E–N–T–I–L–E R–A–N–K“

Ok Percentile Rank Kindly read it loudly

I think it seems like our definition is hard to understand. So to make it easy and to avoid confusion let us recall what is percentile first.

PERCENTILE RANKS are particularly useful in relating individual scores to their positions in the entire group. A percentile rank is typically defined as the proportion of scores in a distribution that a specific scores is greater than or equal to.

So what is Percentile ? A percentile is a 99 score points which

E. Discussing new concept and practicing new skill Very good But the formula to find the percentile rank of grouped data is different in the formula of percentile of grouped data. To solve the percentile rank the formula we use is: Where:

Example 1 Find how many percent of the score are greater than the cumulative frequency of 38 in the table. scores 46-50 41-45 36-40 31-35 26-30 21-25

Frequency 4 8 11 9 12 6

cf 50 46 38 27 18 6

PR = percentile rank, the answer will be percentage = cumulative frequency of all the values below the critical value P = raw score or value for which one wants to find a percentile rank LB = lower boundary of the kth percentile class N = total frequency i = size of the class interval

So who wants to solve on the board 38 is within 36 – 40 LB = 35.5 P = 38 N = 50 = 11 = 27 I=5

= 65

There for 65% of the scores are less than the cumulative frequency of 38, while 35% of the scores are greater than the cumulative frequency of 38.
