python 2.7 - Using SciPy to find probability in case of non-Normally Distributed Curve -


i have percent array, failed normal test using scipy. means cannot use z_score calculated using array's average , standard deviation , use 

stats.norm.cdf(z_score)

this give incorrect probability z_score per normal distributed curve.

how pass array percent_data scipy, such creates distribution curve internally , how pass z_score corresponding function returns correct probability ?
