Random sample = All of the population have an equal chance of being selected
Quota sample = Candidates are chosen based on their characteristics
Quantitative data = Data in numerical form

PED = percentage change in quantity demanded/
percentage change in price
PED > 1 then demand changes more than the price changes
PED < 1 then demand changes less than the price changes
Elastic demand = PED is greater than 1
Inelastic demand = PED is less than 1
Unitary elasticity = PED equals to 1
Income elasticity of demand (YED) = The correlation between income and the quantity demanded
Market share = The amount a firm sells as a percentage of the total sales of the market
Market share = (Sales of the product /Total market sales) x 100
