If a distribution has a mean of 50 and a standard deviation of 25,how many standard deviations is 0 from the mean?
A) 2
B) -2
C) 0
D) 5
Standard Deviations
A statistic that measures the dispersion or spread of a set of data points relative to their mean.
Mean
The average of a set of numerical values, calculated by summing them up and dividing by the number of values.
Deviation
In statistics, it refers to the difference between the observed value and the mean of a dataset, indicating how much the data points diverge from the average.

Final Answer :
B
Explanation :
To find how many standard deviations a value is from the mean, subtract the mean from the value and divide by the standard deviation: (0 - 50) / 25 = -2.
