What else can I help you with?
How can you describe what is typical about the distribution of a set of data?
The answer will depend on the set of data!
When is the mean not a valid statistic to describe a set of data?
The population data may be skewed and thus the mean is not a valid statistic. If mean > median, the data will be skewed to the right. If median > mean, the data is skewed to the left.
How is the choice made between mean and median to describe the typical value related to the shape of the data distribution?
Either can be used for symmetrical distributions. For skewed data, the median may be more a appropriate measure of the central tendency - the "average".
What is a set of data collected to answer a statistical question?
It is simply a data set.
What is the minimum data value in a data set?
The minimum data value in a data set is simply the lowest value of the set (easily found by arranging the set from lowest-highest values in an excel sheet or by hand).
How can you describe what is typical about the distribution of a set of data?
The answer will depend on the set of data!
How can you describe what is typical about a set of data?
the averaged amount of the data given to you
What are the numbers used to describe the center of a set of data?
data pattern
What are the numbers that describe a set of data called?
It could be the cardinality of the set.
How can you describe variation in a set of data?
measures of variation
Which set of data can be describe classified as quantitative?
Y
What is the shape of each distribution in a data set?
The distributions can have any shape that you like.
What does the measure of central tendency describe in a data set?
It describes the "middle" of the data set.It describes the "middle" of the data set.It describes the "middle" of the data set.It describes the "middle" of the data set.
How can you describe a set of data in a spreadsheet?
A set of data can be described to the spreadsheet as a range by specifying the beginning cell, in the upper left corner of the data, and the ending cell, in the lower right corner of the data.
Which measure of cetral tendency would be appropriate to describe this data set?
None. The data set has no elements and so there cannot be any central tendency.
The three characteristics that describe a set of numerical data are?
mode, mean and median
What is a single number used to describe a set of data mean median mode?
2,5,4,5
