Symmetrical distribution in statistics and an example?

mean deviation is minimum


What is the minimum data required for standard deviation?

The standard deviation is a measure of how spread out the numbers are. Three points is needed to calculate a statistically valid meaningful standard deviation.


What is a measure of the width of a distribution of a set of numbers that includes the range the iqr and standard deviation?

The width of a distribution can be measured using several metrics, including range, interquartile range (IQR), and standard deviation. The range provides the difference between the maximum and minimum values, while the IQR represents the spread of the middle 50% of the data, indicating variability without being affected by outliers. Standard deviation quantifies the average distance of each data point from the mean, offering insights into the overall dispersion of the dataset. Together, these measures provide a comprehensive view of the distribution's width and variability.


What is the minimum grade a student must get in order to receive an A's if the mean grade was 72 and the standard deviation was 9?

Different examinations have different thresholds for A grades.

What do standard deviation error bars indicate when they go past your minimum value?

If the minimum value is the minimum observed value then it indicates that the distribution goes below the minimum observed value.If the minimum value is the minimum defined for the distribution then it indicates thatthe data do not come from the proposed distribution,estimates for the mean or standard deviation are incorrect, oryou have got a sample which is atypical.


Can standard deviation value be bigger than maximum and minimum value?

No standard deviation can not be bigger than maximum and minimum values.

When will the minimum deviation occur in the experiment of the spectrometer-refractive index?

The minimum deviation in a spectrometer experiment occurs when the refracted ray is parallel to the base of the prism, resulting in the prism being in a state of minimum deviation.


What is the advantage of keeping the prism in minimum deviation?

By keeping the prism in minimum deviation position, the RI of the prism can be calculated efficiently.


What is the advantage of keeping the prism in minimum deviation position?

By keeping the prism in minimum deviation position, the RI of the prism can be calculated efficiently.


What is the minimum deviation of prism whose refractive index is three to the power half?

The minimum deviation of a prism can be calculated using the formula: δ = (n - 1)A, where δ is the minimum deviation, n is the refractive index of the prism, and A is the angle of the prism. If the refractive index of the prism is three to the power of half, or √3, and the value of A is known, the minimum deviation can be calculated using the formula.
