What is Xi in statistics?
Xi usually refers to an observation or a value in statistics. It is the i'th observation. If there were 10 observations, X5 refers to the fifth observation. In general, Xi refers to the ith observation where i may range from 1 to 10 in this case.
What does statistical question mean?
A statistical question is one that anticipates variability in the data and seeks to gather information to analyze that variability. Unlike a simple question with a definitive answer, a statistical question typically requires data collection and statistical methods to answer. For example, "What is the average height of students in a school?" is a statistical question because it involves measuring and analyzing the heights of multiple students.
What statistical concept is used to explain the natural difference that exists between a sample mean and corresponding population mean?
Random error.
What is a statistical question mean?
A statistical question is one that anticipates variability in the data and can be answered by collecting and analyzing data. It typically involves a population or a sample and is designed to yield insights based on statistical methods. For example, asking "What is the average height of adult men in a city?" is a statistical question because it considers variations in height among individuals. In contrast, a non-statistical question would be one with a definitive answer, such as "What is the height of the tallest man in the world?"

What does observation mean in statistics?
a row means an observation if there are many rows.
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)

What is A countable or measurable observation called?
A countable or measurable observation is referred to as a "quantitative observation." This type of observation involves data that can be expressed numerically, allowing for statistical analysis and comparison. In contrast, qualitative observations are descriptive and subjective, focusing on characteristics that cannot be measured numerically. Quantitative observations are essential in scientific research for drawing objective conclusions.
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.
