Infinite: not possible to study the whole population, sample is a part of the population, n = sample size, steps. 5"4 : when you collect data you have to analyze it, you can graph your found data. N = 13: small group = survey. Pilot survey: rough draft from own experiences. General survey: real survey that creates final results: population = census, simple random sample: probability of including any items in the sample will be the same. Quantitative = height in number (5"4 ) (enumeration) Qualitative = height in words (short, average, tall) (categorical) If data is continuous, you need to make a table and later on we will graph f. If sample size is too large, categorize data into groups.
