EXST 2201 FINAL EXAM QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTIONS GRADED A++
Word form =
Qualitative
What are the two types of Qualitative?
1. Nominal (name only)
2. Ordinal (has order)
Numeric form =
Quantitative
What are the two types of Quantitative?
1. Discrete (can be counted)
2. Continuous (can take on multiple values)
Split into know groups & pull randomly from them =
Stratified Study
Has a designed outcome (measurable) =
Designed Study
Asking for a response & not applying any treatment =
Observational Study
The same people are tested before & after an experiment (dependent test) =
Matched pairs
, The researcher doesn't know what people are placed in what group & who gets
what treatment =
Blind doubles
Random with people who matters =
Random sampling (best one)
What is cumulative frequency?
Take the frequency and add the one under it (& to the side), to it
What is relative frequency?
The percentage (frequency/ total)
Orders the bars from the highest frequency to the lowest from left to right =
Pareto chart
Radom bars that are high and low frequencies =
Bar chart
When the bar chart is cut and folded in half you get the same look =
Symmetrical Histogram
When the bars are starting high on the left and getting lower to the right =
Skewed Right
When the bars are starting high on the right and getting lower to the left =
Skewed Left
Mean =
Average (add all the numbers up & divide by the # of values)
Median =
(50/ 100) x N
