我們選用鮮乳產品並以年齡分層作顯著差異的比較，並統計消費者購買人次，將各年齡分層統計的實際值與理論值利用誤差度公式算出誤差值結果是162.0748946，明顯得知有顯著差異。

結果 (英文) 1:

We use fresh milk products and to compare the significant differences stratified by age and statistical consumers to buy people, of all ages will be stratified statistics of actual and theoretical values ​​calculated using the formula error value of the error is the result 162.0748946, obvious that there significant differences.

結果 (英文) 2:

We select fresh milk products and use age stratification to make a significant difference in comparison, and statistics consumer slated the number of times, the actual value of each age stratification statistics and theoretical values using the error degree formula to calculate the error value result is 162.0748946, obviously learned that there are significant differences.

結果 (英文) 3:

We select fresh milk products and make a significant difference comparison with age stratification, and count the number of consumers' purchases. The error value calculated by the error formula between the actual value and the theoretical value of each age stratification is 162.0748946, which shows that there is a significant difference.
