yes is it the median?
For which measure of central tendency will the sum of the deviations always be zero?
Difference (deviation) from the mean.
average is defined as a single value which has tendency to represent the data as a whole. averages are also called "measure of central tendency" or "measure of location"
the mean %100
The geometric mean can be used to find average percent change over a period of time.
The average or mean is one measure of central tendency. There are several.
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.
yes it is, but it is actually called central tendecey just like( the median and mode)
Mean or average is the most common measure of central tendency of a sample.
No. The average of the deviations, or mean deviation, will always be zero. The standard deviation is the average squared deviation which is usually non-zero.
that which is either two or three standard deviations (a statistical measure of variability) below the normal average head circumference for the age, gender, and race of the child.
It is the mean.
Generally IQ measures are standardized so that an IQ of 100 is the average score for the norming population, and standard deviations can vary from 10 to 15, depending on the measure used.
True-as in an average.
3 common Measure of central tendency are the mean, median and the mode. They are measures in that they tell how how far any given value is from the center of a set of data. For example, the mean is commonly known as the average. Lets say you have the test scores, 25%, 50% , 75% and 100% You wonder how your 50% is compared to the mean? Since the mean is 62.5, you performed "below average." So that measure of central tendency measured how far you were from average. The others do the same thing.
Megalencephaly (also called macrencephaly) describes an enlarged brain whose weight exceeds the mean (the average weight for that age and sex) by at least 2.5 standard deviations (a statistical measure of variation).
X-bar represents the mean or average of the sample variable.
