Describing Data
100
The entire collection of what is to be studied
What is a population?
100
This is the shape of a normal distribution.
What is symmetric?
100
This type of data must be numeric and the distance between consecutive values is measureable.
What is quantitative data?
100
A distribution which is unimodal, peaks on the right and has a tail on the left.
What is skewed to the left?
100
This is an unusually low or unusually high value in the dataset.
What is an outlier?
200
This is a subset of a population or process.
What is a sample?
200
This normal distribution has a mean of 0 and a standard deviation of 1.
What is a standard normal distribution?
200
This type of data measures a quality or characteristic and has no meaningful order.
What is nominal data?
200
This distribution is characterized by having two peaks.
What is a bimodal distribution?
200
This measure of spread tells us the average distance values are from the mean.
What is the standard deviation?
300
A characteristic of a sample.
What is a statistic?
300
This is the area beneath the entire normal distribution.
What is 1?
300
This type of quantitative data is usually the result of a count.
What is discrete data?
300
This distribution is unimodal, peaks on the left and has a tail on the right.
What is skewed to the right?
300
These are two ways to present a dataset containing 100 students' GPAs?
What is a histogram, boxplot, stem and leaf plot or dotplot?
400
A characteristic of a population or process.
What is a parameter?
400
Almost the entire distribution is found within the mean plus or minus this many standard deviations.
What is three?
400
This type of quantitative data is usually the result of a measurement.
What is continuous data?
400
This distribution has two halves on either side of the center which look approximately like mirror images of each other.
What is a symmetric distribution?
400
This is the result from squaring the standard deviation.
What is the variance?
500
The natural tendency of randomly drawn samples to differ, one from another.
What is a sampling variability or sampling error?
500
This percentage of the distribution is found within the mean plus and minus two standard deviations.
What is 95%?
500
This type of data measures a quality or characteristic and does have meaningful order.
What is ordinal data?
500
All the bars in this distribution are approximately the same height.
What is a uniform distribution?
500
This measure of location tells us how many standard deviations a value is from the mean.
What is a z-score or standard score?
