You look outside and realize that your grass needs to be mowed. You pick up the container of gasoline and see that you have approximately a third of a gallon left. You hypothesize that this amount will be enough to mow your entire lawn. Unfortunately, half way through mowing your lawn you run out of gasoline. You grumble and think to yourself that the next time you mow the lawn, you hypothesize that you will need to have at least two-thirds of a gallon of gasoline available. How did the results of your lawn-mowing experience influence the validity of your new hypothesis for future gasoline needs

My prediction of future gas needs is founded on experimental data and hence increases the validity of my hypothesis.

Explanation:

Experimental data is a term that simply described the data derived through various past experiences or manipulation such as measurement of length or sizes of objects under consideration.

Hence, in this situation, my prediction of future gas needs is founded on experimental data gathered from previous experience and hence increases the validity of my hypothesis.
