Yes.
Given any set of n numbers it is always possible to fit a polynomial of order (n-1) that will generate the set of data.
For example, consider 2, 4, 8, 16, 32.
It is the sequence of numbers defined by
Un = 2n where n = 1, 2, 3, ...
But then consider Vn = (n4 - 6n3 + 23n2 - 18n + 24)/12 for n = 1, 2, 3, ...
These generate the same sequence for n = 1 to 5. Unless the data set is infinite, there is always the polynomial alternative. And that is not the only option.
no * * * * * Yes, almost always. If you have n data points which are 1-to-1, then it is always possible to fit a polynomial of degree n-1 or greater.
A number that describes numerical data is a Statistic.
Data is neither a table nor a graph, however, data may be presented in a table or depicted by a graph.
You do not convert any data in Excel. A table is a layout to organize the data. If you want the data to look like it is in a table, then move the data to where you would like it to display.
Range, variance, and standard deviation usually are used to describes the spread of data.
no * * * * * Yes, almost always. If you have n data points which are 1-to-1, then it is always possible to fit a polynomial of degree n-1 or greater.

A pattern describes many observations but does not explain them. Patterns may be observed in data or phenomena, but the underlying cause or mechanism behind the pattern is not fully understood.

a data table is a table to place your observations
Table walking is a method used in data analysis to systematically move through rows or columns of a table to extract or manipulate data. It involves iterating through each row or column to perform calculations, comparisons, or other operations. This technique is commonly used in data processing tasks such as filtering, sorting, or aggregating data in a structured format.

A ratio table is more like a pattern, where a data table has graphs.
