It was felt that the take up possible use was made of the equipment and come outs available in order to extend to reliable data under the time constraints involved.The sampling size for this investigating was set at 30 this allowed a reasonably large sample and thus reasonably c onfident deductions and tests are possible for the Analysis and valuation sections. However, a sample size of 30 is tranquilize small luxuriant in order to feasibly collect data within the allocated time period.The both sites chosen were suitable in order for logical data to be collected and compared. The two sites were comprehensively distinct sun and shade sites. As can be seen on the photograph, the sun site had virtually no major branches or trees in its vicinity and thus a stripe of light was able to shine on the leaves. In contrast, the shade site was surrounded and shadowed ... ...ns, it has to be stated that the validity of the results have been undermined and the conclusion is certainly stated with less confidence. The accumulation of so many sources of error seems to suggest that the conclusion may even be an altogether nonsensical one due to unreliable collection of data. However, the sources of error do not change the conclusion itself. Pieces of evidence such as the significant differences in means, use of standard deviation and the comprehensiveness of the t-test suggest that the conclusion is still a valid one. Although the data is not completely normally distri scarceed, the 99.999% confidence at which the t-test accepts the hypothesis is considerable. Certainly, these limitations suggest that that percentage is unlikely to be that high, but given the nature of the investigation and results ascertained, the conclusion is still a valid one.
