EDA REVIEW Flashcards
Ranked data set into 100 equal groups of data.
Percentile
Ranked data set into 10 equal groups of data.
Decile
Determines the position of a single value in relation to other values in a sample or a population data set; also called Quantiles or Fractiles.
Measures of Position
It is a score distribution where the scores are divided into different equal parts.
Quantiles
The most commonly (frequent) occurring value in a distribution.
Mode
The total value of an observation in a data set divided by the number of observations.
Mean
The middle value in distribution when the values are arranged in ascending or descending order.
Median
Called the average or central location and a summary measure that describes a whole set of data with a single value that represents the middle of its distribution.
Measures of Central Tendency (MCT)
Pertaining to quantity, numeric data.
