Which are ways to improve the design of this experiment? check all that apply. -reduce the sample size so the experiment can be done faster. -increase the sample size from 6 cups to 12 cups of sand and water. -use more legible handwriting when recording data. -use more precise digital thermometers. -use more precise scales that measure to the hundredth of a gram.

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.

The answers to this question are as following: -increase the sample size from 6 cups to 12 cups of sand and water.-use more precise digital thermometers-use more precise scales that measure to the hundredth of a gram
