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
How do you know which measure of central tendency best describes the data?
The answer will depend on the nature of the data.If the data are qualitative then the only option is the mode.If they are ordinal then you have a choice between the mode and median. The mode may be a better measure when the data are very skewed. Otherwise the median is usually better.For any higher level of measurement is is also possible to calculate the mean. In such cases the median or mean are better. For very skew distributions the median is better but otherwise is should be the mean.
Can ypu find the mean and median with data from a histogram?
You can estimate the median and the mean.
What do mean by Data Handling?
what do you mean by data handling define mean mode median
How can you find mean median and mode for GROUPED data?
Mean, median and mode are ways to find averages. The mode is the most common answer in a set of data. The median the number that is in the middle when the numbers are put in order. The mean is the statical average.

Which measure of central tendency cannot be applied to ordinal data?
The mean cannot be used with ordinal data. The best measure of central tendency for ordinal data is usually the median. A common example of ordinal data is the scale you see in many surveys. 1=Strongly disagree; 2=Disagree; 3=Neutral; 4=Agree; 5=Strongly agree. The mean would have not meaning here ( no pun intended) The median is simple the middle value. The mode does have meaning.

What central tendency can be used on ordinal data?
For ordinal data, the median is the most appropriate measure of central tendency, as it effectively represents the middle value in a ranked order. While the mode can also be used to indicate the most frequently occurring category, the median provides a better summary of the data's central point, especially when the data is not symmetrically distributed. The mean is generally not suitable for ordinal data due to the lack of equal intervals between ranks.
In deciding which average to use which is most and worst reliable out of mean modal and median?
The mean is used for evenly spread data, and median for skewed data. Not sure when the mode should be used.
Does all data have a mean median or mode?
No, not all data sets have a mode but all data sets have a mean and median.

Are the mean median and mode always numbers from a list of data?
the median and mode are but the mean is not
What is mean and median?
mean~ all the numbers in the data added together divided by the number of data. The mean is the same as the average. median~ the exact middle of the set of data. Example: 1,1,2,2, the median is 1.5 mean- the average median- the middle number in a set of numbers in a group.Example of Median-1,3,5,7,9,4,5 (put them in order and list them from least to greatest)1,3,4,5,5,7,9the median is 5!

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.
