1. statistics: science of data: collecting, classifying, summarizing, organizing, ana-
lyzing, and interpreting info
2. data: things about which info can be collected and analyzed
3. data set: an arranged collection of info that contains the various categories of
data collected for a specific study
4. element: the individual and unique entry in a data set about which data has been
collected, analyzed, and presented in the same manner
5. variable: a particular, measurable attribute that the researcher believes is needed
to describe the element in their study
6. observation: all the info collected for each element in a study
7. descriptive statistics: a complied summary of the data analysis (tabular, graph-
ical, or numerical forms) (uses numerical and graphical methods to explore data,
look at patterns, summarize info, present info)
8. inferential statistics: the use of a sample to make decisions about a population
9. population: the entire number of items in a large group
10. sample: a smaller representative group from the population
11. qualitative data: observations classified into a group of categories, not on a
numerical scale (can be numerical or categorical). Examples are age, gender)
12. quantitative data: measurements recorded on a naturally occurring numerical
scale (# of children, grade pt average, bank account amount, temperature)
13. t/f: math operations only make sense on quantitative data: true
14. what are the two types of data collection: cross-sectional and time series
15. what type of data collection is where data is collected at the same or
approximately the same point in time, such as a lap time in race or average
GPA of one semester of students?: Cross-sectional data
16. what type of data is collected over several time periods, such as the
average price/gallon of gas over a decade?: time series data
17. t/f: the most commonly used numerical statistic is called the aver-
age/mean: true
18. statistical inference: uses sample data to make estimates, decisions, predic-
tions or other generalizations about a larger set of data or population
19. where do you find data (2 options): existing info or direct collection
20. what are the two forms of direct collection for statistical studies: experi-
mental and observational (active/passive)
21. what type of statistical study is this?
researcher reviews a situation, identifies variables that influence the elements
in the study, and manipulate some variables and keep others constant to com-
1/2
