BUSN 3000 Exam 1-Graded A
Research Question - correct answer-Broad scoped question
Statistical Question - correct answer-Response-based, no singular answer, must
analyze data
Response variable - correct answer-What is being measured, what we would like to
predict (i.e. y-axis)
Explanatory variable - correct answer-What calculates the predictions and impacts the
dependent-variable (i.e. x-axis)
Column(s) - correct answer-In a data table, variables are displayed in...
Row(s) - correct answer-In a data table, cases are displayed in...
Identifier - correct answer-Uniquely identifies each individual case, organizes the data
Quantitative variable - correct answer-Variable that can be measured numerically
Categorical variable - correct answer-Variable that cannot be averaged, includes
whether or not questions
Cross sectional data - correct answer-A snapshot, the data is measured once
Time series data - correct answer-Data that is measured repeatedly, changes over time
Sample - correct answer-A small subset of the population, aims to accurately estimate
the parameter
Census - correct answer-A sample that includes the entire population, expensive, time-
consuming, impossible to eliminate non-response bias
Randomization - correct answer-Technique that eliminates unconscious bias and
provides a representative sample
Sampling error - correct answer-The statistic will vary from sample to sample depending
on the group selected, error that is purely due to randomness, 100% okay
Increase the sample size - correct answer-How can sampling error be reduced?
