Technique for collecting data

Since my experiment will be involving many different numbers i will need to put my results into a table and graph so that i can clearly analyse my results without being confused.
By placing my results into a table and a graph it will be easier for me to identify the factors that need to be taken into consideration , such as the rate it takes the tablet to dissolve in hotter water rather than cooler water. This is very important for me to visualise as i will need to discuss and conclude my results.

I have designed my table where i will later on place my results into to :

Condition	Reaction TIme  ------------------------------------- Trial 1 | Trial 2 | Trial 3	Average Reaction Time ( s)
Normal Water ( Room Temperature water )
Cold water ( iced water )
Hot Water ( Boiled water )

My next step was to set out my graph , now this was tricky. I had to decide on whether i was going to do a column graph , bar graph or a line graph.
I came to the conclusion to do a line graph as i knew my data could be easily read on this graph .
