What provides a measure of central location for the data?
mean
Is range a measure of central location?
No, it isn't. Mean, median, and mode are the three most common measures of central location (although there are others). These measures of central location are attempts to find the middle value of a range.
Is median a measure of central location?
Yes, the median is a measure of central location. It represents the middle value of a data set when the values are arranged in ascending or descending order. The median effectively divides the data into two equal halves, making it a useful measure, especially in skewed distributions where it provides a better central tendency measure than the mean.
Which measure of central location will the sum of the deviation of each value from the data's average will always be zero?
the mean %100
What is the sum of all deviations of a data value from a measure of central location that will always be zero?
Difference (deviation) from the mean.

If a frequency distribution has open-ended intervals at the extremes which measure of central location is the most difficult to estimate?
mean
For which measure of central location will the sum of the deviations of each value from the data's average will always be zero?
The mean.

Which measure of central location will the sum of the deviation of each value from the data's average will always be zero?
the mean %100
What is the sum of all deviations of a data value from a measure of central location that will always be zero?
Difference (deviation) from the mean.
What measure of central location is used to determine an average annual percent increase?
The geometric mean can be used to find average percent change over a period of time.
What is the prime measure of central tendency is the?
Median
What is the difference between central tendency and average or mean?
The average or mean is one measure of central tendency. There are several.
Which measure of central tendency mean mode median is used for IQ?
The mean.
When is using the mean useful?
When you want the central location of a variable.
