Trapezoidal membership function is widely used for its simple form and the low requirement for data. But it can't reflect objective facts very well. On the basis of data, this paper gives a kind of membership function by using the statistical approach so as to eke out trapezoidal membership function. Trapezoidal membership function is regarded as an especial example of this membership function. The arithmetical example makes it clear that this membership function reflects objective facts better.
