Explain why the mean does not best represent the data?
well because in the mean you have to add them and its different from the median and the mode
Which measure of central tendency best represents data?
Median
What measure of center best represents data?
The answer depends on the type of data. The mean or median are useless if the data are qualitative (categoric): only the mode is any use. The median is better than the mean is the data are very skewed.
Is median better indicator of central tendency of skewed distribution?
Yes. Central tendency is the way data clusters around a value. Even if the distribution of the value is skewed, the median would be the best indicator of central tendency because of the way the data is clustered.
What type of graph is best for revealing the median of a set of data?
box-and-wisker

What is median in the set of data?
The median in a set of data, would be the middle item of the data string... such as: 1,2,3,4,5,6,7 the Median of this set of data would be: 4
What type of graph would be best to represent numerical data?
BAR ;)
What is a median in arithmetic?
The median is the "middle" number in a set of data or a sequence. If you have the sequence 2,3,4,5,6 4 would be the median.
Which measure of central tendency best represents data?
Median
What measure of central tendency may not exist for all numeric data sets?
Measurement Scale Best measure of the 'middle' Numerical mode Ordinal Median Interval Symmetrical data- mean skewed data median Ratio Symmetrical data- Mean skewed data median
Can the median be greater than the 1st quartile in a data set with 1000 values?
The median must be at least as great as the first quartile in any data set. Normally it would be greater.The median must be at least as great as the first quartile in any data set.

What is the median of five?
Median is only meaningful with a set of data. The median of five would just be five. Similar to asking what the average of 5 is.
Is median better indicator of central tendency of skewed distribution?
Yes. Central tendency is the way data clusters around a value. Even if the distribution of the value is skewed, the median would be the best indicator of central tendency because of the way the data is clustered.
When might you want to use the median to describe the center of a data set instead of then mean?
You would use the median if the data were very skewed, with extreme values.
