CENTRAL TENDENCY Flashcards
defined as the difference between the highest value
and the lowest value in the data set.
Range
It is numerical value indicative of a typical value
Of the distribution.
Measurement of central tendency
It is associated with the interval and ratio data
Mean
It is associated with ordinal data
Median
It is associated with nominal data
Mode
In measure of central tendency what is the measurement that it is affected by the extreme value in a set of data?
Mean
When do we say that the distribution is symmetrical?
If the distribution is normal
If mean is greater than median median is greater than mode what is the distribution?
Skewed to the right
If the mean is less than the median in the median is less than the mode what is the distribution?
Skewed to the left
What are the two properties of median
Even number
Odd number
It is what we called the pulled out layer
Extreme value
It is not representative of other data set
Extreme value
It is when you cannot calculate the mean if the data set has a
Open minded class interval
It may or may not exist and may not always unique
Mode
What do we called when the data is categorized or categorical
Nominal data
What do we call the data when the measure is by rank
Ordinal data
What do we call when the data is numeric or numerical measurement
Interval and ratio data
What the practices are observation when the median is a middle value
Odd number
What practices or observation when the median is the average of two values
Even number
It is the 10 equal parts
Deciles
