In late spring, a student began conducting an investigation about the flower preferences of bees. She counted the number of wildflowers in a small plot and created the following table. Plant Species Number of Plants Dandelion 13 Indian paintbrush 8 Queen Anne’s lace 20 Thistle 29 She planned to observe the flowers for the next five days for an hour at the same time each afternoon. Then she would plot the data in a multiple line graph to compare the number of bees that visited each flower. Which statement best describes the data in this investigation? The data would be more accurate if she carried out all the observations in one day so weather conditions would be constant. The data would be more valid if she made the observations daily for two months. The data she collected is inaccurate because the investigation is not repeatable. The data she collected cannot be plotted in a line graph because it is qualitative.
Answers
Analysis of the experiment :
1) The observations are made once everyday at the same time for one hour.
2) A variety of plant species are used in the experiment.
3) Line graphs are then drawn separately for the flowers.
Weaknesses of this experiment.
1) The student did not perform the experiment at different times of the day because this also would make the study more detailed.
2) The time set for the observations was also limited hence maximum observations could not be made.
The correct answer is thus :
statement best describes the data in this investigation? The data would be more accurate if she carried out all the observations in one day so weather conditions would be constant.
.
After reading the experiments the student did in investigating the flower preferences of bees, it can be said that the best sentence to describe the experiment is "The data would be more valid if she made the observations daily for two months".
It is a known fact that any experiment becomes a success after its done time and time again.
The more times you do an experiment, the higher the accuracy of your result will be.
