Standard Deviation क्या है?
Standard deviation मापता है राशि की variation या dispersion में a dataset. A low standard deviation इंगित करता है values are close को the mean, while high standard deviation इंगित करता है values are spread out. It है widely used में finance को measure volatility, में manufacturing के लिए quality control, और में research को measure डेटा reliability. Sample standard deviation (n-1) provides एक unbiased estimate के लिए population डेटा.
उपयोग कैसे करें
Enter your dataset values separated द्वारा commas, spaces, या new lines. Select whether your डेटा प्रतिनिधित्व करता है a sample (using n-1) या the entire population (using N). The कैलकुलेटर गणना करता है standard deviation, variance, mean, median, range, coefficient की variation, और other statistical मापता है.
अक्सर पूछे जाने वाले प्रश्न
What is standard deviation?
Standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
What is the difference between Sample and Population?
Use 'Population' when your data set includes every member of the group you want to study. Use 'Sample' when your data represents a subset of a larger group. The calculation formulas differ slightly (Sample divides by N-1, while Population divides by N) to provide an unbiased estimate.
How do I input my data?
You can enter numbers separated by commas, spaces, or new lines. For example, you can paste a column directly from Excel or a CSV file. The calculator will automatically filter out non-numeric characters.
What is Variance?
Variance is the square of the standard deviation. It represents how far each number in the set is from the mean. While standard deviation is expressed in the same units as the original data, variance is expressed in those units squared.
Why is my result 0?
A standard deviation of 0 means that all the numbers in your data set are exactly the same. There is no variation or spread between the values.
What does Count (N) mean?
Count, often represented as 'N', simply refers to the total number of valid data points or observations you have entered into the calculator.
