Complete Solution
Human computer - ANSWER one who computes
First digital computer - ANSWER Abacus
Atanasoff-Berry Computer (ABC) - ANSWER Invented in 1937 by Atanasoff to speed
up solutions of math problems. There was no patent on it which allowed people to
steal his ideas. Went to court in 1973 and recognized John Atanasoff as the inventor
of the electronic digital computer which annuled ENIAC patents.
ENIAC - ANSWER Electronic Numerical Integrator and Computer. Credited to Eckert

Charles Cole - ANSWER Patent lawyer that had to prove the ENIAC was based on
Atanasoff's computer.

different values.
Nominal Variable - ANSWER A variable that has values that cannot be ranked and

and have equal distances between adjacent values. Ex: income measured in dollars.
Happiness in countries video - ANSWER - Based on many factors like democracy,
economic growth, and personal choice.
- Canadians are happier than americans
- Rank among the top happiest countries in the world
Survey design - ANSWER 1. Research question and/or hypothesis
2. Select sample
3. Questionnaire must be created using official languages.
4. Type of survey must be chosen.
5. Pilot testing.
Reserach hypothesis - ANSWER A statement that we want to prove or disprove with
the help of research
Research question - ANSWER A question that we want to answer with the help of
research.
Population - ANSWER All cases about which one seeks knowledge. Ex: all uOttawa
students
