Action Plan for Success 1 – Read the text chapter before seminar 2 – Attend seminar(s) 3 – Watch the MML tutorials and do the MML tutorial practice 4 – Complete the MML Project and text practice problems (as needed, the odd numbered problems) 5 – Start the Word Project (located in Doc sharing) 6 – Post to the discussion board throughout the week.

Ask Questions! Do not wait until Tuesday night. Office Hours: By appointment. Phone questions any time. Tutoring is available in the Math Center most days and evenings. Go to My Studies, Academic Support Center on the Kaplan page. Tutoring is also available through Pearson, MML Tutoring Services link is under Course Home.

Seminar Rules and Structure Usual format of seminar will involve discussion of a concept and then responding to questions I post on the concept. Posting a wrong answer will not negatively affect your participation grade. It is more important that you try to participate rather than simply watch. Social posts (It is raining, Hi, Bye, My car broke down) will not help your participation grade.

Types of Data Quantitative data Quantitative data has a value or a numerical measurement for which you can calculate sums, products and other numerical calculations. You can measure it, miles per gallon, weight, age, etc. Qualitative data Qualitative data is grouped into a category or group. Sums, products or other numerical calculations do not mean anything. You can only count it, football jerseys, assigning numbers to gender, college major, state of residence, etc.

Population, Sample, Data Sets Population: The collection of all outcomes, responses, measurements, or counts that are of interest Sample: A subset of the population Data Sets: The information coming from a population or sample.

Classifying a Data Set Determine if the data set comes from a population or sample The age of every member of the Senate A survey of 300 home owners in a town with 34,000 homes.

Identify the Population and Sample A survey of 1500 adults in the United States found that 25% prefer Sprite. A study of 50 children in one school was conducted to find a link between school performance and eating a good breakfast.

Levels of Data Measurement, page 14 Nominal: Data is put in categories using names, labels, or qualities. Examples : names of cities, political parties, telephone numbers. Ordinal: Data is put in ordered categories or ranked. Differences between data entries are not meaningful. Examples: ranking of cities or TV shows; small, medium, large

Levels of Data Measurement Interval: Data can be ordered and calculations made. Subtraction is meaningful. A zero entry is a position on a scale, not an inherent zero point. Examples: temperature, highest grade level completed, year of graduation Ratio: Data can be ordered, calculations made, and it has an inherent zero point. A data point can be meaningfully expressed as a multiple of another data point. Examples: Heights of corn plants, terms in school, snowfall amounts, taxes paid

Sampling The KEY for all statistical analysis is the sample has been randomly drawn. Types of Random Samples –Simple –Stratified –Cluster –Systematic Non-Random Samples –Convenience

Sampling Random sampling – every group of size n in the population has an equal chance of being selected. Stratified sampling – population is divided into strata, a random sampling is conducted for each strata Cluster sampling – population falls into naturally occurring clusters, randomly sample clusters Systematic sampling – assign numbers to each member of the population, select every nth number Convenience sampling – sample whoever is available Question: Would this class be a representative sample of Kaplan University students?
