What is the formula for calculating variance and standard deviation?
b-a/6
How can I calculate the calories per watt of energy expended during my workout?
To calculate the calories per watt of energy expended during your workout, you can use the formula: Calories burned (Watts x Time) / 4.18. This formula takes into account the power output in watts and the duration of your workout to determine the calories burned per watt of energy expended.
How can I calculate portfolio variance in Excel?
To calculate portfolio variance in Excel, you can use the formula SUMPRODUCT(COVARIANCE.S(array1,array2),array1,array2), where array1 and array2 are the returns of the individual assets in your portfolio. This formula takes into account the covariance between the assets and their individual variances to calculate the overall portfolio variance.
How do you find variance?
You calculate it using the appropriate formula, which, given the limitations of this site, is not easy to reproduce. However, you can easily Google the formula.
How do you calculate total material variance?
Total material variance is calculated by comparing the actual cost of materials used to the standard cost of materials that should have been used for the actual production level. The formula is: Total Material Variance = (Actual Quantity x Actual Price) - (Standard Quantity x Standard Price). This variance can be further broken down into material price variance and material quantity variance for more detailed analysis.
What is the total deviation formula used to calculate the overall variance in a dataset?
The total deviation formula used to calculate the overall variance in a dataset is the sum of the squared differences between each data point and the mean of the dataset, divided by the total number of data points.
When do we use the unbiased formula of variance?
Variance is a characteristic parameter of a probability distribution: it is not a statistic. In any particular situation (with a few strange exceptions) it has only one value and therefore cannot have any bias.
What is the Direct labor efficiency variance formula?
(actual time * standard rate) - (standard time * standard rate)
Accrued interest vs interest payable?
Interest payable is the interest that has not yet been paid to the customer on the deposit. Accrued interest is interest that is accumulated over a period ,especially from last payment made to the customer. The primary formula for calculating the interest accrued in a given period is: where, T = number of days in the period/number of days in the year
What is the power expended if a boy pulls a sled up a hill is 425 J in 10.5 seconds?
To calculate power, you can use the formula: Power = Work / Time. In this case, the work done is 425 J and the time taken is 10.5 seconds. Plugging these values into the formula, the power expended by the boy to pull the sled up the hill is 40.48 watts.
What is the formula used to calculate the variance of a set of data?
The formula to calculate the variance of a set of data is given by: [ \sigma^2 = \frac{1}{N} \sum_{i=1}^{N} (x_i - \mu)^2 ] for a population, where ( \sigma^2 ) is the variance, ( N ) is the number of data points, ( x_i ) represents each data point, and ( \mu ) is the mean of the data set. For a sample, the formula adjusts to: [ s^2 = \frac{1}{n-1} \sum_{i=1}^{n} (x_i - \bar{x})^2 ] where ( s^2 ) is the sample variance, ( n ) is the number of sample points, and ( \bar{x} ) is the sample mean.
What is the variance used for?
Variance is used to add standard deviations when comparing two samples or populations. Variance is simply Std^2. The formula for obtaining Std is dependent on the type of sample taken\ hypothesis test performed i.e. 2-proportion pop/sample, single proportion, poussin, binomial, etc.
