Question

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.

Answer 1

The correct option is this: THE DATA WILL BE MORE VALID IF SHE MADE THE OBSERVATION DAILY FOR TWO MONTHS.
In scientific investigation, the number of trials executed is very important, because the higher the number of trial the higher the accuracy of the experiment. The student would have obtained a more valid result if she extend the number of days she use to carry out the investigation.
