Other commonly used names for Phi are: Golden Mean, Extreme and Mean Ratio, Divine Proportion and Golden Ratio. Phi is a naturally occurring ratio which exhibits aesthetically pleasing properties.

What is 1 phi approximately equal to?

The golden ratio or golden mean, represented by the Greek letter phi (ϕ), is an irrational number that approximately equals 1.618.

Is phi a whole number?

7.1 Phi is not a fraction But Phi is a fraction .. it is (√5 + 1)/2. Here, by a fraction we mean a number fraction such as 2/3 or 17/24 or 12/7. The first is a proper fraction since it are less than 1. Also 5.61 is a fraction, a decimal fraction since it is 561/100, the ratio of a whole number and a power of ten.

How do you write phi?

What does Φ mean in statistics?

The phi correlation coefficient (phi) is one of a number of correlation statistics developed to measure the strength of association between two variables. The phi is a nonparametric statistic used in cross-tabulated table data where both variables are dichotomous.

What is Phi equal to?

Phi is the second in an infinite sequence of n-nacci constants which all satisfy the equation;- F + 1/F^n =2. In the case of n=2 we get;-Phi + 1/Phi^2 =2 ;(Where Phi = The Fibonacci constant) When n=3 we get the Tribonacci constant n=4 gives the Tetranacci constant n=5 gives the Pentanacci constant
