The mean of a set of data is the sum of that data divided by the number of items of data.
One reason I can think of why you might not be able to find the mean of numerical data would be if there were missing data points.
To find the first deviation of a dataset, you first calculate the mean (average) of the data points. Then, for each data point, subtract the mean to find the deviation from the mean. The first deviation is typically the result from the first data point, which is the difference between that data point and the mean. This process helps in understanding how each data point varies from the average.

To find the mean on a dot plot, first sum the values represented by the dots. Then, divide that total by the number of dots (or data points) present in the plot. This will give you the average value, or mean, of the data set. The dot plot visually displays the distribution, helping you understand the data alongside the calculated mean.
To find the missing mean in a set of data, you first need to know the sum of all the values in the data set as well as the total number of values. Once you have this information, you can calculate the missing mean by dividing the sum of all the values by the total number of values. This will give you the average value of the data set, which is the missing mean.
find assumed mean data is 46,55,52,59,63,47,56,50,51,55 ,
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.

when there are extreme values in the data
The data point is close to the expected value.
You can estimate the median and the mean.
Th find the mean of a data set, you add up all the values in the data set and divide this sum by the number of data values. For example, the mean for the data set 2, 5, 6, and 7 is given as 2 plus 5 plus 6 plus 7, which is 20. You divide this sum by number of values in the data set, which is 4 to get 5 as the mean.
The ''mean'' is just another term for average. To find the mean, you must add all of the data together and divide that number by the number of pieces of data. Hope this helped! ~Maci~
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.
You can estimate them both.
