Which measures of central location always have only one value for a set of grouped or ungrouped data?
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
MeAN of ungrouped data?
Add it all together, and then divide it by the number of data entries that there are.
How can you find the assumed mean of grouped data?
find assumed mean data is 46,55,52,59,63,47,56,50,51,55 ,
How is a frequency distribution used?
it is used to find mean<median and mode of grouped data
For a symmetric distribution of data the mean is equal to which other quantity?

How do you solve ungrouped data?
You cannot "solve" ungrouped data since ungrouped data is not a question. You can calculate the mean or the variance, standard deviation or skewness, or a whole range of other measures for ungrouped data. But you have not specified what.
Difference between group and ungrouped data?
Ungrouped data is the raw data, and correct statistics such as the mean and standard deviations can be determined. Ungrouped data is usually the starting point of analyses. Grouped data means there is less data to work with and my statistics will be approximate. But we work with grouped data all the time, and so long as the interval is not too big, there's no problem. It is frequently necessary to group the data to observe trends. I will give you an example: If I say there have been 10 million accidents in the last 20 years and 5 million in the interval from 20 years to 40 years ago, it doesn't tell me much. But if I present data of the number of accidents in the last forty years, by year, this is grouped data given in a meaningful manner.

What does ungroup mean?
The word ungroup or ungrouped usually refers to data. It is separate data or line items separate from other groups within the code or package.
What is the Standard deviation of a set of data in which all the data values are the same?
ZeroDetails:The "Standard Deviation" for ungrouped data can be calculated in the following steps:all the deviations (differences) from the arithmetic mean of the set of numbers are squared;the arithmetic mean of these squares is then calculated;the square root of the mean is the standard deviationAccordingly,The arithmetic mean of set of data of equal values is the value.All the deviations will be zero and their squares will be zerosThe mean of squares is zeroThe square root of zero is zero which equals the standard deion
