what is meaning of ñ in maths
Answers
Answer:
It means the median of a series of data values representing a variable like temperature, pressure, volume, marks, mass, weight, cost, price, profit etc.
Step-by-step explanation:
The symbol tilde on top of an alphabet like n represents the statistical median of a set of data values. Remember mean, median and mode ? that is the one.
This median is the median in statistics that represents an approximate mid value of the data set..
If there are N number of data values in a data set n , then
ñ = the (N+1)/2 th data value if N is odd,
= the average of the N/2 th and (N+2)/2 th data values if N is even.
For example:
n = {4, 2, 6, 9, 7, 10, 3 }
ñ = 9 = median of variable n as it is the 4 th value (N = 7).
Further, ñ has more meanings.
The tilde operator on top of capital D means the differentiation operator d/dx which is extensively used in mathematics, sciences and even in macro economics.
The tilde operator on top of an alphabet represents a new operation defined by a scientist or engineer for his data set of values. That symbol is used in many research papers in that way.
