Statistics - correct answer ✔the study of how to collect, organize, analyze,
and interpret numerical information from data
Descriptive statistics - correct answer ✔Methods of describing data
inferential statistics - correct answer ✔Methods to draw conclusions about
the population the data comes from
Population - correct answer ✔All members of a specified group
Sample - correct answer ✔A part of a population used to describe the whole
group
Variable - correct answer ✔An object, event, idea, feeling, time period, or
any type of category you are trying to measure
Independent variable - correct answer ✔Stands alone and isn't changed by
other variables you are measuring
dependent variable - correct answer ✔A variable that depends on other
factors
quantitative data - correct answer ✔Information about quantities, can be
measured and written down with numbers
, Quanlitative data - correct answer ✔Information about qualities, information
that is not measured with a numerical scale for various reason
Bias - correct answer ✔Error in design or executive of a study which
produces inaccurate results
Misuse of statistics - correct answer ✔When statistical argument asserts
something false or misleading, maybe intentional or accidental
Variability - correct answer ✔A measure of how each score in a group of
scores differs from the mean
3 types of variability - correct answer ✔Range, standard deviation, variance
Range - correct answer ✔The most general estimate of variability, tells the
range between highest and lowest data point
Standard deviation - correct answer ✔The most reported measure of
variability
Average amount of variability in a set of scores
The measure of how spread out the numbers are
Variance - correct answer ✔Measures how far a set of numbers is spread
out
A variance of zero means all values are identical
=standard deviation squared
Notation of mean in sample - correct answer ✔x̅
