Table 2: Results of two sample T-tests, where the eggplants 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||4.15||0.8||5.21||1.42||0.03||Equal variances||0.05|
|Day 4||4.69||0.85||5.64||1.39||0.04||Equal variances||0.1|
|Day 7||6||1.08||5.21||1.42||0.12||Equal variances||0.1|
|Day 11||7.23||1.17||8||1.36||0.13||Equal variances||0.6|
|Day 18||10.77||1.59||9.64||1.69||0.09||Equal variances||0.83|
|Day 25||16.85||4.51||12.36||1.91||4.30E-03||Different variances||4.23E-03|
|Day 32||32.15||9.61||17||3.19||8.15E-05||Different variances||3.58E-04|
|Day 39||44.08||12.2||18.93||3.93||4.73E-06||Different variances||2.63E-04|
|Day 46||61.46||12.36||21.36||5.39||8.66E-09||Different variances||5.62E-03|
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.
