Scientific method cannot answer all questions
Science can figure out what happened to the universe (big bang), but not what
caused the big bang
Science cannot answer ultimate question for example what happen to us when we
die?
Science cannot answer ultimate questions because they are not empirical (facts)
Past experiences filters your perception, helps to shape how we see reality
Reality is biased
Putting biases out there for everyone to see before the experiment will tell everyone
the biases in the outcome
Descriptive trend (observational trend)
1.From 1952 to 2002 the divorce rate rose from 15% to 50% of all marriages
Descriptive static (data)
1. Infant mortality rate in Canada in 2001
2.Population in Scarborough in 2009
Explanatory studies (tries to explain facts)
1.The children of upper income parents are more likely to attend university
2.Does the economy influence rate of common crime
Both descriptive & explanatory studies are commonly used by governments to implement
policies (Social accounting)
Census states that most Canadians are aging (descriptive trend)
Starting in 1946 there is a baby boom (explanatory study)
In 1960s, trend analysis is used by government to build more schools to
accommodate the raising population born during the baby boom age
CPP (Canadian Pension Plan) will go broke as the baby boomers are getting old now
One solution is to raise retirement age to 70 (less payout)
