Introduction to Statistics and Probability Flashcards
It is a collection of methods for planning experiments for obtaining data and analyzing, interpreting, and drawing conclusions base on the data.
statistics
It is a measure or quantification of the likelihood or chance that a particular event will occur.
probability
The basic terms in statistics.
- data
- variable
- population
- sample
It is a basic term in statistics wherein the values that the variables can assume.
data
It is a basic term in statistics wherein it is observable or measurable in every unit of the population.
variable
It is a basic term in statistics wherein it is the set of all possible values of a variable.
population
It is a basic term in statistics wherein it is a subgroup of a population.
sample
The two classifications of variables.
qualitative and quantitative
It is a classification of variables that refers to words/codes that represent a class or category.
qualitative variable
It is a classification of variables that expresses a categorical attribute.
qualitative variable
It is a classification of variables that refers to the following:
- gender
- marital status
- religion
qualitative variable
It is a classification of variables that refers to the number that represent an amount or count.

quantitative variable
It is a classification of variables that refers to the following:
- weight
- height
- family size
quantitative variable
The two classifications of quantitative variable.
- discrete variable
- continuous variable
It refers to data that can be counted.
discrete variable
It can assume that all the values between two specific values like 0.6, 1.2, etc., and data that can be measured.
continuous variable
The 2 levels of measurement.
- Nominal Level
- Ordinal Level
It is a level of measurement that is characterized by data consist of names, labels, or categories only.
nominal level
It is a level of measurement that refers to the following:
- gender
- most preferred color
- civil status
- usual sleeping habit
nominal level
It is a level of measurement that involves data that are arranged in some order, but differences between data.
ordinal data
It is a level of measurement that refers to the following:
- highest education attainment
- academic rankings
ordinal level
The formula in getting probabilities.
P (probability of) = favorable outcome/total outcome
