What is Xi in statistics?
In statistics, Xi represents an individual data point or observation within a dataset. It is commonly used to denote the ith data point in a sequence of data. The subscript i is used to differentiate between different data points in the dataset, with i typically ranging from 1 to n, where n is the total number of data points. Xi is a fundamental concept in statistical analysis and is essential for calculating various statistical measures and conducting data analysis.
What statistical concept is used to explain the natural difference that exists between a sample mean and corresponding population mean?
Random error.
What does the z score of 1.3 mean?
It means that there is a probability of 0.0968 that an observation as extreme as this occurred purely by chance.
What is positional average?

Mean of 25 observation is 36 but mean of first 13 observation is 32 and mean of last 13 observation is 40 find 13nth observation?
25 x36 = 900 13 x 32 = 416 13 x 40 = 520 ----- 936 936-900 = 36 (13th observation)
Does a set of values mean the same as an observation?
No. One observation will normally get you onevalue, not a set of values. Also, to be precise, the observation is the act of observing; the value is the result of the observation, not the observation itself.
How do you increase the mean in math?
Add an observation that is bigger than the mean or remove an observation that is smaller than the mean.
