Is the mean of the grouped data is equal to the mean of ungrouped data?
Suppose you compare the mean of raw data and the mean of the same raw data grouped into a frequency distribution. These two means will be
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.
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.
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 ,
Is it true that in large data sets the mean is always one of the data values?
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
Why is mean a measure of the center of the data?
mean does not mean the center of the data
Why is the mean a measure of the center of the data?
mean does not mean the center of the data
What do you mean by data assembly?

Find the mean of the data?
The mean of a set of data is the sum of that data divided by the number of items of data.
Does the mean have to be a member of the set of data?
no. Some mean is a number from the data but some mean is completely different from its data.
What does sensory data mean?
Its mean incomplete data or the data upon which we can not rely totally.
Is the mean of the grouped data is equal to the mean of ungrouped data?
Suppose you compare the mean of raw data and the mean of the same raw data grouped into a frequency distribution. These two means will be
What do mean by Data Handling?
what do you mean by data handling define mean mode median
How does the outlier affect the mean of the data?
An outlier does affect the mean of the data. How it's affected depends on how many data points there are, how far from the data the outlier is, whether it is greater than the mean (increases mean) or less than the mean (decreases the mean).
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.
What is mean data?
Mean data are observations whose values are equal to the mean of the data set. By default it is the arithmetic mean but it could be the geometric or harmonic mean - if those measures are more appropriate.
What does interpretation of data mean?
