Basically I want to look for the differences between storage periods and bacterial counts. However, I don't know which tests that I can use to determine the significant differences. For example, the storage periods are 0, 3 and 6 months meanwhile for the bacterial counts are recorded in CFU with triplicates readings. So, how I want to input the data in SPSS? I'm confuse.
Thank you.
Jamal,
You can do One way ANOVA test for your results based on deferent months. According to your test,
H0- There is no deference between the storage time and bacterial count
H1 -There is a deference between the storage time and bacterial count
You can process SPSS or MINITAB software to analyze the test and if your p value similar or lessthan 0.05 that means your null hypothesis rejected and H1 accepted.
