To determine which statement best describes the data in this investigation, let's carefully evaluate each statement based on the conditions and aims of the investigation.
### Evaluation of Statements
1. The data would be more accurate if she carried out all the observations in one day so weather conditions would be constant.
- While observing the flowers under constant weather conditions could reduce variability due to weather changes, it does not account for the natural fluctuations in bee behavior over different days. Observing in a single day could actually limit the scope and reliability of the data due to potential anomalies or outliers on that specific day.
2. The data would be more valid if she made the observations daily for two months.
- Observing for an extended period, such as two months, would provide a more comprehensive dataset. This method would account for daily and seasonal variations, offering insights into long-term trends which would improve the validity of the data. This approach recognizes the intrinsic variability in natural biological systems and accounts for it effectively.
3. The data she collected is inaccurate because the investigation is not repeatable.
- Repeatability is important in scientific investigations as it ensures that the results can be consistently reproduced under the same conditions. However, concluding that the data is inaccurate solely because it is not repeatable is not entirely accurate. Lack of repeatability affects reliability and validity more than the inherent accuracy of a single set of observations.
4. The data she collected cannot be plotted in a line graph because it is qualitative.
- This statement is incorrect because the data is quantitative, as it involves counting the number of bees visiting each flower. Quantitative data can indeed be represented in a line graph, enabling a visual comparison of the number of bees over the observation periods.
### Conclusion
Upon reviewing the statements, the best choice is:
The data would be more valid if she made the observations daily for two months.
This is because it recognizes the importance of capturing data over a longer period to account for natural variability, thereby improving the validity and robustness of the investigation.
Therefore, the correct choice is 2.
