What does a probability distribution with high variance indicates?
Wiki User
∙ 14y ago
There are several things that will cause a large variance. One would be a large spread in the data; the other is the data may contain an outlier(s) that is causing it or a combination of both.

What does a higher z-score tell you about a specific data entry?
A high z-score indicates an observation that is further away from the mean. This indicates that either the observation is less probable or that assumptions about the distribution are wrong.
A sentence with the word probability?
"There is a high probability of rain this evening."
How is this relevant to marketing Assume the frequency that a household purchases milk per year is a normal distribution with a mean of 12. Over time the mean stays the same but the variance decreases?
It should make marketing easier because the amount purchased has a smaller variance. This means that the numbers are closer to 12 and so there is less of a need to carry large stocks for when the demand is high.
What is a good sentence for probability?
There is a high probability that this sentence will not qualify as a good sentence.
What is the probability of the mean being greater than 78?
A very high probability if your numbers are greater than 78.
Can heritability be negative value?
Yes, but negative variance indicates environmental variance (i.e., within-family or within-strain) is unusually high, possibly due to poor experimental design. Narrow sense heritability (h2, not H2) = (phenotypic variance - environmental variance) / phenotypic variance.
What does a higher z-score tell you about a specific data entry?
A high z-score indicates an observation that is further away from the mean. This indicates that either the observation is less probable or that assumptions about the distribution are wrong.
What does it mean for a trait to have low variance?
A trait that has low variance suggests that there is a high environmental variance. This means that the success of a trait is increased if people are raised in optimal environmental conditions.
A sentence with the word probability?
"There is a high probability of rain this evening."
Is likely a preposition?
"Likely" is an adverb that indicates a high probability or possibility of something happening. It is not a preposition, which are words that show the relationship between a noun or pronoun and other elements in a sentence.

Is the probability of a mutation at a particular gene locus high or low?
The probability of a mutation at a particular gene locus is low, and the probability of a mutation in the genome of a particular individual is high.
Does low variance lead to high inter rater reliability?
No, low variance does not necessarily lead to high inter rater reliability. Inter rater reliability is focused on the consistency of ratings between different raters, while variance measures the spread or dispersion of scores within a dataset. It is possible to have low variance but still have low inter rater reliability if raters are consistently scoring inaccurately or inconsistently.
What is a good sentence for probability?
There is a high probability that this sentence will not qualify as a good sentence.
What is the probability of getting a sum greater than 9?
there is no end to numbers so the probability is very high
What is the probability of being possessed?
That depends on many factors. For example, if you are a $1 bill, the probability is quite high, whereas if you are a human being, the probability is quite low.
What is the significance of variance in statistics?
Variance is a measure of "relative to the mean, how far away does the other data fall" - it is a measure of dispersion. A high variance would indicate that your data is very much spread out over a large area (random), whereas a low variance would indicate that all your data is very similar.Standard deviation (the square root of the variance) is a measure of "on average, how far away does the data fall from the mean". It can be interpreted in a similar way to the variance, but since it is square rooted, it is less susceptible to outliers.
