DEFINITIONS
A science that studies data and is used as a tool for decision-making processes.
STATISTICS
A variable that does not change.
Constant Variable
The number of schools in the Philippines.
Discrete
What is the possibility of getting both heads while flipping two coins?
1/4 probability
The likelihood of an event occurring.
PROBABILITY
A variable whose value is obtained by counting.
Discrete Variable
The total height of all the students in a classroom.
Continuous
List out all the probability of flipping 4 coins.
S: {TTTT, TTTH, TTHT, THTT, HTTT, TTHH, THTH, HTTH, HHTT, HTHT, THHT, THHH, HTHH, HHTH, HHHT, HHHH}
It is used to represent the function of a probability distribution.
Pr(x)
A variable whose value is obtained by measuring.
Continuous Variable
The temperature of the box when exposed to a sun.
Continuous
Shown in the histogram, what is the likelihood of not getting all tails?
15/16 probability
The summation of all probabilities.
∑Pr(x) = 1
A variable that can be manipulated or under a researcher's control.
Active Variable
The number of prime numbers you can see in a measuring tape.
Discrete
Shown in the histogram, what is the probability of getting less than or equal to 2 heads in flipping 4 coins?
11/16 probability
The range of all possibilities in an event.
0 < Pr(x) ≤ 1.
It is the output being studied and termed as criterion, response, presumed outcome, or effect.
Dependent Variable
The number of floors satisfying the height to be considered to be a building.
Discrete
From the histogram shown, what is the probability of having more than 2 heads of flipping 4 coins?
5/16 probability
