What type of distribution of a set of data that shows nearly the same frequency for all values?
The Uniform Distribution.
What does uniform mean in math?
Uniform probability can refer to a discrete probability distribution for which each outcome has the same probability. For a continuous distribution, it requires that the probability of the outcome is directly proportional to the range of values in the desired outcome (compared to the total range).

Which is better non uniform?
Choosing a non-uniform distribution can be better than a uniform distribution when the data closely follows real-world scenarios or when certain values are more likely to occur than others. Non-uniform distributions can provide a better representation of probability in many practical situations, allowing for more accurate modeling and analysis.
How do you calculate the error of a median for a non-parametric distribution?
You would need to take repeated samples, find their median and then calculate the standard error of these values.
Why is population distribution not uniform all over Nepal?
In probability theory and statistics, the continuous uniform distribution or rectangular distribution is a family of symmetric probability distributions such that for each member of the family, all intervals of the same length on the distribution's support are equally probable. The support is defined by the two parameters, a and b, which are its minimum and maximum values. The distribution is often abbreviated U(a,b). It is the maximum entropy probability distribution for a random variate X under no constraint other than that it is contained in the distribution's support
How do you calculate chi square p values?
You could calculate it by integrating the chi-square probability distribution function but you are likely to be much better off using a table in a book or on the web.
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 find chi square if only one frequency table is given?
You seem to be referring to the Pearson chi-square test-of-fit statistic. To do this you need not only the observed values in a frequency table (which you have) but the expected (or theoretical) values for that table.In practical situations the expected values are obtained by making some educated guess about what distribution the observed values came from, estimating the parameters of that distribution and then using the estimated distribution to obtain the required expected values to calculate the chi-square.In short, you need more information.
What does data distribution mean?
It is the set of values that a variable can take together with the probability or frequency distribution for those values.
How do you calculate count frequency?
To calculate the frequency of counts in a dataset, you count the number of occurrences of each unique value in the dataset. This helps you understand the distribution of values and identify the most common or rare occurrences within the dataset.
How do you calculate Kullback-Leibler divergence-distance KLD?
The KLD is more or less a measure of how much information is lost when an approximation is used to replace an actual probability distribution. How you calculate it depends on whether you are considering discrete or continuous values for the distribution. If you have discrete values, KLD = Σ P(i) log [P(i)/Q(i)] (summing over the values of i) where P(i) is the "true" distribution and Q(i) a corresponding approximation. If you have a continuous function for the probability, i.e. the variable can assume any value over a certain range (usually with different probability density for different values since uniform probability is a pretty boring problem) KLD = ∫ p(x)log[p(x)/q(x)] dx (integrated from -∞ to +∞) where p(x) is the true function of the probability - the "density" of P, and q(x) is the approximated function of the probability - the "density" of Q. Note that these formulas only hold for a single variable. More complex formulas are required to calculate the KLD for multi-variable distributions.
