Statistical distribution
STRANDS OF STUDY

Descriptive Statistics:
•Experimental Statistics
•Probability
•Data, trends, graphs
•Experiments, observation

Theoretical Statistics:
•Confidence Interval
•Normal Distribution
•Percentile

DEFINITIONS

• Data: Facts and properties for items/objects
•Population: the entire collection of objects that is considered
•Sample: a subgroup of the population that represents the whole
•Bias: When the sample does not represent the population
•Census: When the sample does represent the population
•Discrete data: values considered in whole units counted
•Continuous data: values can be considered in fractions measured
TYPES OF DATA REPRESENTATION


Mean for categorical data Mean for grouped data Mean of a:

Population

Sample Example: Mean for categorical data Example: Mean for grouped data By: Juliana Pattermann
Ian Tam Example: Cumulative data distribution Measuring the spread of data:
the box-and-whisker plot Variance and Standard Deviation "Bell curve" normal distribution Experimental probability Theoretical probability Example: Grid to find probability Types of events Tree diagrams Sampling with / without replacement Venn Diagrams Probability laws Discrete random variable Expected value Mean and standard deviation Do give us good marks, Mr. Hung.
