Back to the Basics!
This field of study examines how to collect, organize, analyze, and interpret numerical information.
What is statistics?
This research method is also known as "people-watching".
What is observational research?
This graph organizes categorical data and always should add up to 100.
What is a pie chart?
This measure of central tendency is also known as the "average" of a dataset.
What is the mean?
This method of determining how likely an event is to happen can also be described as our "gut feeling".
What is intuition?
This level of measurement primarily helps us organize categorical data.
What is nominal data?
This research method is the only method that can offer a cause-and-effect relationship.
What is experimental research?
This graph organizes numerical data and specifically measures time.
What is a line graph/time chart?
This measure of variability examines the overall spread of the data by subtracting the smallest data value from the largest.
What is the range?
What is the probability of flipping heads once?
What is 1/2 or 50%?
This level of measurement includes a true zero point.
What is ratio?
In survey research, this type of variable can mess with your overall results and their interpretation.
What is a lurking variable?
This graph's defining feature is that the bars are always touching each other.
What is a histogram?
This measure of central tendency examines the middle point of the dataset.
What is the median?
When we have an AND probability, we do this to the two probabilities.
What is multiply?
This sampling method pulls people from readily attainable groups.
What is convenience sampling?
This phenomenon results when participants believe that they have received the experimental treatment even though they actually haven't.
What is the placebo effect?
This distribution shape happens when the histogram is not symmetric.
What is skewed?
Here is a dataset: 2, 3, 6, 9. Please find the mean of the dataset.
What is 5?
When we have OR probabilities, we do this to the two probabilities.
What is add?
This sampling method pulls participants from groups that are naturally occurring in a population.
What is stratified sampling?
Give me an example of a lurking variable.
What is (any answer that correctly shows a lurking variable in action)?
What is the third step of the process of creating a frequency table & histogram?
What is tally the data into classes?
Here is a dataset: 2, 3, 6, 9. Please find the standard deviation of this dataset.
What is 3.16?
What is the probability of drawing a Jack OR a spade?
What is 16/52?
