3. Population: – The total number of inhabitants of a particular species in a given area. – A collection of individuals subject to a statistical study. Collecting Data Sample: A small group chosen from the population. – Random Sample: is one where each element has the same chance of being included. – Biased Sample: is one that is not random. Conclusions about a population can be made by collecting data from a sample (portion) of that population.

4. Types of Data Qualitative Data – Describes a particular quality or characteristic. It is data that can be divided into categories and is not given numerically. – i.e. color of eyes or types of ice cream Quantitative Data – Contains a numerical value. The data collected is termed numerical data. – Discrete – Takes exact number values and is often the result of counting. i.e. number of TVs or number of houses on a street – Continuous – Takes numerical values within a certain range and is often a result of measuring. i.e. the height of seniors or the weight of freshman Describing Data

5. Classify these as qualitative, quantitative discrete or quantitative continuous: a)The number of heads obtained when 3 coins are tossed. b)The brand of toothpaste used by the students in our IB Math Studies class. c)The heights of a group of 15 year old teenagers.
