means that there is a positive relationship between taste and purchasing decisions, the better of the taste, the more
purchasing decisions increase.
4. Color variable regression coefficient (X3) of 0.031; this means that if other independent variables have a constant score and
the color has increased 1%, then the purchase decision (Y) will experience an increase of 0.031. Positive coefficient means
that there is a positive relationship between color and purchasing decisions, the better of the color, the more purchasing
decisions will increase.
5. Nutrition variable regression coefficient (X 4) of 1.124; this means that if other independent variables have a constant score
and nutrition has increased 1%, then the purchasing decision (Y) will experience an increase of 1.124. Positive coefficient
means that there is a positive relationship between nutrition and purchasing decisions, the better of the nutrition, the more
purchasing decisions will increase.

Determination coefficient

Multiple linear regressions in determination analysis were conducted to get the contribution presentage of the influenced
independent variable on dependent variable simultaneously. Table 3 listed the result of determination analysis.

Table 3 shows that R =0,959 or 95,9%. It shows that the percentage of influence contributes to packaging, taste, color and
nutrition on purchasing decision 95,9%. However, the rest of it 4,1% was influenced by other variables which were nor analysed
on this study.
