This article aims to improving and drawing inferences about population characteristic estimation, some of mathematical methods were used in content of stock market data are collected from Amman stock exchange (ASE) using three methods; point, interval estimation and Wavelet transform (WT) combined with interval estimation. Point estimate can be ambiguous because it may or may not be close to the number actuality estimated. Themethodology is to compare between the point and interval estimations then the estimation has improved by combining WT with theinterval estimation in order to reduce the error. The results show that (WT) with interval estimation is the best method, (SPSS) and mat lab 2010a have used in this study.
