What else can I help you with?
Is the mean 50 percentile of any normal distribution?
Yes, the mean (and median and mode) is the 50th percentile of any normal distribution.
In an uniform distribution is the mean and median the same?
Yes, they are. A uniform distribution is one in which the probability of each outcome is the same and, as a result, the mean and median are the same. A uniform distribution should not be confused with a set of random variables, all with the same distributions - much less the same values!For example, the median of a Poisson distribution is not the same as its mean. So if you have a number of random variables (RVs), each with the same Poisson distribution, their mean and median will be different. This is true of any set of RVs whose distributions are asymmetric.And it is very easy to see that the mode need not be the same. The outcome of a single roll of a regular die is the uniform distribution over the numbers {1, 2, 3, 4, 5, 6}. The mean and median are 3.5 but the mode cannot be 3.5 since that is not a value that can ever be observed.
How can you calculate median?
The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two. Ex. (10, 17, 20, 45, 68) The median is 20.
What characteristics about the Standard Normal Distribution make it different from any normal distribution?
The mean is 0 and the variance is 1. This need not be the case in any other Normal (Gaussian) distribution.
What are some applications of normal distribution in your daily life?
Following are some applications:- 1)Computing grades from test scores by using the bell curve to find the average. 2)Same applies to any other normally distrubuted quantity like height,weight etc. • The normal distribution is a distribution that is centered around an average value with an even spread in both directions (standard deviation). • This makes the distribution symmetrical! • This symmetry causes the mean, median, and mode to be the exact same value. • Symmetry will come in handy when calculating probabilities.
In which situations mean and median are not same?
If there is any skewness in the distribution.
If the mean is 40 in a normal distribution what is the median?
In a normal distribution, the mean, median, and mode are all equal. Therefore, if the mean is 40, the median is also 40. This property holds true for any normal distribution regardless of its specific values.
Can mean and median have one value?
Yes. And in any symmetric distribution, they will.
Is the mean 50 percentile of any normal distribution?
Yes, the mean (and median and mode) is the 50th percentile of any normal distribution.
In an uniform distribution is the mean and median the same?

Why do you use mean median and mode?
Together they tell you more about a series of numbers that any one of them. mean - average median - middle number if the numbers are listed from smallest to largest mode - most common number If your mean and median are close to one another, the statistical distribution is usually fairly good. Likewise, if the mode is close to the mean and median, it gives more verification that the distribution is a nice bell curve. The mode is probably the least useful of the three, as it assumes that there are many repeating numbers. In many actual situations, there aren't enough repeating numbers to make the mode of any value.
What is the median of 616773768287?
The median of any single number, such as 616773768287, is itself.
Is forty a median number?
Any number can be a median, so for the correct set of values, 40 could be a median.
What is the median of 12131415161718192021?
12131415161718192021. The median of any single number is just that number.
What is the median for 41832923?
The median of any set of numbers is its middle value in ascending order
In a negatively skewed dist. following statements are true except?
In a negatively skewed distribution, the mean is typically less than the median, and the median is less than the mode. This results in a tail that extends longer to the left. Therefore, any statement claiming that the mean is greater than the median or that the mode is less than the median would be false. Thus, one must be careful to identify which statements accurately reflect the characteristics of negatively skewed distributions.
What ratio does a median divide two equilateral triangle?
A median divides any triangle in half.
