Aquasol Concentration Of Barley Raids

Discussion:
Shown in tables 1 and 2, the shoot heights, on average, of the barley seeds, increased as the Aquasol concentration increased. This is with the exception of the solution with an initial Aquasol concentration of 0.40% in Table 1, which showed to have, on average, shorter shoot heights in comparison to the solution with 0.25% Aquasol. Ultimately, this indicates that the experiment had random and systematic errors that affected the accuracy, reliability, validity, and precision of the results. That being said, the results imply that, overall; barley seed germination and seedling growth became more effective, as the Aquasol concentration increased. This may be due to the fact that Aquasol contains the essential nutrients, nitrogen,
As a result, the precision of the data is lowered, and thus, becomes less reliable. One incident where this may have occurred is seen in the average shoot height calculated for the sample with 0.40% Aquasol in the first week of the experiment, where the average shoot height was lower than that of the sample with 0.25% Aquasol. Inconsistent measuring of the 0.50% Aquasol solution could also be an inconsistent error, as if more or less than 100mL of the 0.50% Aquasol was used during dilution, the formula y/100=0.50/(x+100) would have not been valid, and thus, the concentration of each Aquasol solution would have not been as assumed. The final concentration of Aquasol for each solution may have been different to that of what was expected, and hence, the shoot heights measured would have not corresponded to the assumed concentrations. This would result in unreliable data with very low precision. Likewise, inconsistent measuring of the volume of deionised water required to dilute each solution would have resulted in a random error. This is because if the volume of deionised water measured is incorrect, and different to that of the one calculated using the formula y/100=0.50/(x+100), the concentration of the Aquasol would be different to that of the desired concentration. Hence, the shoot heights measured for each solution would not correspond to the expected concentration, making the results unreliable. Moreover, inconsistent spraying of the Aquasol concentrations onto the petri dish could have been a random error, as this would have meant that some barley seeds germinated in a more or less moist environment than others, hence, causing the barley seeds to germinate either more or less effectively than others. This is because moisture is a condition critical to the
