A statement of deviations is a financial document that compares actual performance against budgeted or expected figures, highlighting variances in revenues, expenses, or other financial metrics. It helps organizations identify areas where performance deviates from plans, enabling management to analyze the causes of these differences and make informed decisions. This statement is essential for effective financial control and strategic planning, ensuring that corrective actions can be implemented when necessary.

How many standard deviations is 16.50 from the mean?
How many standard deviations is 16.50 from the mean?
I have two data sets with the same number of values with means x1 and x2 and standard deviations of n1 and n2. How do you average means with standard deviations?
You can't average means with standard deviations. What are you trying to do with the two sets of data?
What is the z-score of a value that is 2.08 standard deviations greater than the mean?
The z-score of a value indicates how many standard deviations it is from the mean. If a value is 2.08 standard deviations greater than the mean, its z-score is simply 2.08. This means the value lies 2.08 standard deviations above the average of the dataset.
Why don't we measure spread about the mean by simply averaging the deviations of individual data values from their mean?
Averaging the deviations of individual data values from their mean would always result in zero, since the mean is the point at which the sum of deviations is balanced. This occurs because positive and negative deviations cancel each other out. Instead, measures like variance and standard deviation are used, which square the deviations to ensure all values contribute positively, providing a meaningful representation of spread around the mean.
What percentage of scores falls between the mean and -2 to 2 standard deviations under the normal curve?
In a normal distribution, approximately 68% of scores fall within one standard deviation of the mean (between -1 and +1 standard deviations). About 95% of scores fall within two standard deviations (between -2 and +2 standard deviations). Therefore, the percentage of scores that falls specifically between the mean and -2 to 2 standard deviations is about 95% minus the 50% that is below the mean, resulting in approximately 45%.
When you speak your ear drum vibrates.this statement is true or false?
This statement is true. Our eardrums are moved by sound pressure deviations we measure as sound pressure level (SPL) in decibels.
How would you identify and report deviations and what is the significance of deviations?
identify and report deviations
What is the sum of the deviations from the mean?
The sum of standard deviations from the mean is the error.
When was Deviations Project created?
Deviations Project was created on 2007-02-20.
The sum of the deviations about the mean always equals what?
The sum of total deviations about the mean is the total variance. * * * * * No it is not - that is the sum of their SQUARES. The sum of the deviations is always zero.
What does normality mean in health and social care?
All minor deviations occurring with two standard deviations under the Gaussian curve are considered normal. Deviations occurring outside of two standard deviations are considered abnormal.
How many standard deviations is 16.50 from the mean?
How many standard deviations is 16.50 from the mean?
How do you find the sum of squared deviations in a set of numbers?
It would be useful to know what the deviations were from.
What is deviations in homeostasis?
Deviations in homeostasis refer to changes in the body's internal balance or stability. These deviations can be caused by various factors, such as illness, stress, or environmental changes. The body responds to these deviations through regulatory systems to restore balance and maintain optimal function.
Can the standard deviation or variance be negative?
No, a standard deviation or variance does not have a negative sign. The reason for this is that the deviations from the mean are squared in the formula. Deviations are squared to get rid of signs. In Absolute mean deviation, sum of the deviations is taken ignoring the signs, but there is no justification for doing so. (deviations are not squared here)
Which measure of central tendency will the sum of the deviations always be zero?
For which measure of central tendency will the sum of the deviations always be zero?
