The classic example is a Bell curve. IQ testing (using the WAIS, or Wechsler Adult Intelligence Scale) yields a peak at the 100-105 IQ mark, with a downward curve on either side of the peak - representing the higher and lower IQ scores, respectively.
Sampling distribution in statistics works by providing the probability distribution of a statistic based on a random sample. An example of this is figuring out the probability of running out of water on a camping trip.
Not necessarily. Inferential statistics are statistics which are used in making inferences about some distribution. The only requirement is that they are based only on the set of observed values.
The Student's T- Distribution is a type of probability distribution that is theoretical and resembles a normal distribution. The Student T- Distribution differs from the normal distribution by its degrees of freedom.
They are measures of location [of a distribution].
The mean of a sample is a single value and so its distribution is a single value with probability 1.
Why we prefer Normal Distribution over the other distributions in Statistics
It is called a normal distribution.

we prefer normal distribution over other distribution in statistics because most of the data around us is continuous. So, for continuous data normal distribution is used.

It is probably the most widely used distribution in statistics. In addition, a lot of information exists on this distribution.
descriptive
The distribution for a variable is the set of value that the variable can take and the probabilities associated with those value.
The Student's T- Distribution is a type of probability distribution that is theoretical and resembles a normal distribution. The Student T- Distribution differs from the normal distribution by its degrees of freedom.
mean deviation is minimum
i dont even no
