Introduction to Statistics
What is science?
Observations, hypothesis, experiments, proving hypothesis and
being able to replicate it over and over.

Why science?
Alternate isn't good ~ common sense
○
Leads us in the right direction
○
Allows us to set up experiments
○
Allows us to tell the truth from the false
○
•
What are stats?
Organizes data/ info
○
Summarizing info
Charts, tables, mean, standard of deviation
§
○
Compares one set of data to another (Here it starts to get more
complicated)
○
Allows us to draw a conclusion about a set of data
○
•
What part of the plane should we armour?
Too much armour the plane cant move
Too little armour the plane is too easy to shoot down
Section
Bullet holes/ sq feet
Engine
1.11
Fuel system
1.55
Fuselage
1.73
Rest of plane
1.8
Answer: The engine because if it gets more than 1.11 bullet holes then it
will go down.

Document Summary
Observations, hypothesis, experiments, proving hypothesis and being able to replicate it over and over. Allows us to tell the truth from the false. Compares one set of data to another (here it starts to get more complicated) Allows us to draw a conclusion about a set of data. Too little armour the plane is too easy to shoot down. Answer: the engine because if it gets more than 1. 11 bullet holes then it will go down. Variable: a characteristic or condition that can be measured or manipulated. Population or a sample (different equations for samples and populations) We use samples to make inferences on the whole population and hope for the same effect. Need to use bigger samples to verify the accuracy of the data. Parameters: descriptions about the population, typically in the form of a number. Sample size of 10 and average height produced would be a statistic.
