Table 1: Results of two sample T-tests, where the peppers height mean values of aquaponics were compared to those of soil system and the differences were statistically evaluated for p < 0.05, after the two sample test for variance was performed by using OriginPro 2016 (OriginLab, Northhampton, MA).
|Time||Traditional system mean||Traditional system standard deviation||Aquaponic system mean||Aquaponic system standard deviation||Prob > |t|||Two sample test for variance||Prob > F|
|Day 0||21.81||2.66||22.7||2.27||0.38||Equal variances||0.6|
|Day 4||22.67||2.58||23.9||2.43||0.21||Equal variances||0.85|
|Day 7||25.25||2.67||24.8||2.56||0.62||Equal variances||0.91|
|Day 11||27.88||2.94||26.3||2.96||0.18||Equal variances||0.95|
|Day 18||35||3.81||29.3||3.17||2.51E-04||Equal variances||0.54|
|Day 25||43.13||5.62||32.8||3.65||7.65E-06||Equal variances||0.15|
|Day 32||54.75||7.07||36.4||4.17||1.83E-08||Equal variances||0.08|
|Day 39||62.81||8.15||38.2||3.71||3.21E-10||Different variances||0.01|
|Day 46||70.44||8.99||41.5||4.93||1.92E-10||Equal variances||0.05|
Prob > |t| and Prob > F indicate if the p-value was less than 0.05 in the two sample t-tests and two sample tests for variance, respectively.
