Question

A biology class is studying the effect of temperature on the amount of growth of duckweed in an aquarium. What type of data

will they need to collect, and which tools will most likely be used?
o
They will gather qualitative data, using a thermometer and a hand lens.
They will gather qualitative data, using a meterstick and a graduated cylinder
They will gather quantitative data, using a thermometer and a balance
They will gather quantitative data, using a beaker and a timer.
O

Answer 1

They will gather quantitative data, using a thermometer and a balance.

Step-by-step explanation:

This experiment is a type of quantitative research.

Quantitative Reseach:

Studies the effect of an independent variable on dependent variables by collection of quantifiable data that can be subjected to mathematical or statistical tools to draw conclusions.

The students will need a thermometer and balance to note the variation in the temperature of water in the aquarium and to measure the weight/mass of the duckweed respectively. Plotting these values against each other on a graph will give the effect of temperature on the rate of growth of the duckweed.
