That's because of the recent SA, which I had to study for. And although I was (considerably) well-prepared, I screwed the PPAs up...but that's not the point.
The point is that I'm finally back! XD
...with results.
It wasn't the most fun thing to do, trying to present my results, and Excel was being extremely annoying. In any case, I finished the graphs (and they're all line graphs, which are my favourite because I like looking at lines...not so much for quadratics, though).
There was a lot of graphs/charts that could be derived from my data (it was a pain pawing through result after result after result) but I decided only on two types: 1) the number of seeds per day, and 2) average height of sprout per day. That's because I'm testing on germination and growth of the B. rapa over a period of five days, so I needed the seeds and sprouts to be in.
Some may ask why I don't talk about roots, but I thought seeds would be better. Because it really shows how many have grown and how many haven't; roots, on the other hand, can only show how many are in that stage on that day, which may not be very accurate because there is a stage behind and after it (the seed and the sprout).
I can't really explain well, so I have a feeling everyone doesn't get it, but it doesn't quite matter to me...
Anyway, enough (unnecessary) rambling! And here are the results (and my on-the-spot analysis, skip that if you want):
Note: Percentages of seeds are rounded off to 1 d.p.
From the results, it is evident that Group C (control group) germinates more quickly than either Group M (group surviving on cooled microwaved water) or Group C (group surviving on cooled boiled water). Group M follows after, while Group B's seeds seem to fare the worst.
In percentages, 75.0% of Group C has germinated by the fifth day while 50.0% of Group M has germinated by the fifth day. 41.7% of Group B germinated by the fifth day.
For average height of sprouts, sprouts below 0.5cm are not included, and all heights are rounded to 1 d.p.
Group C sprouted first, with an average height of 0.7cm on Day 3. On Day 4, all groups sported sprouts; Group C increased by 1.7cm in average height, while Group M and Group B showed a 1.6cm and 0.9cm increase respectively. Increase in height slowed from Day 4 to 5 - Group C increased by 0.6cm, Group M increased by 0.2cm, and Group B increased by 0.4cm.
On all days, Group C has the largest average height, followed by Group M, then Group B.
Group C (control group) germinates the fastest; 77.1% of the seeds in Group C has germinated by the fifth day. Group B, which originally fared the worst, had exponential growth between Day 4 and 5, and 60.4% of its seeds germinated by the fifth day. Notably, there were errors in the tabulation of Group B's data, seen from the sudden increase in seeds on Day 3.
Group M's germination continued steadily, but stalled between Day 4 and 5, where only 1 seed germinated. 35.4% of Group M's seeds germinated by Day 5.
Much like the first experiment, Group C sprouted first, with an average height of 0.8cm on Day 3. On Day 4, Group M sprouted as well, increasing exponentially to an average height of 1.5cm, while Group C increased by 1.7cm, undefeated by Group M.
Growth slowed for Groups C and M on Day 5 - Group C increaed by 0.4cm while Group M increased by 0.2cm. Group B sprouted on Day 5, with an average height of 1cm (however, it has very, very few sprouts, seen in the raw data, but unseen in this table).
Note: The green line is Group B instead of Group C.
Experiment 3 was marked by a sudden onslaught of rainy weather, leading to an increase in humidity and decrease in evaporation. The toilet paper were moist throughout most days, thus leading to an increased rate of germination in seeds.
Group M's germination rate was the quickest at first, with 89.6% of the seeds having germinated by Day 2. On the same day, Group C had 66.7% of its total amount of seeds germinated, and Group B follows after, with 52.1% of its seeds germinated. On Day 3, however, Group M's germination rate stalled, and Group C had an exponential increase in germination - both Groups M and C had 95.8% of their seeds germinated. This means that Group M had a 5.8% increase in germinated seeds while Group C had a 28.9% increase in germinated seeds. Group C lagged behind, with 93.8% of its seeds germinated.
On Days 4 and 5, it is noted that Group M and Group B did not witness any germination in seeds, while Group C's seeds continued germination until it has achieved 100% germination.
Group C led on all days, and all groups sprouted on Day 3. Group C's average height was 1.7cm, followed by Group B at 1.5cm and Group M at 1.3cm. On Day 4 Group C increased by 1.2cm, while Groups B and M increased by 0.9cm.
Group C continued a steep incline, ending with an average height of 4 cm and an increase of 1.1cm. Group B, however, had a slowed growth from Day 4 to Day 5, increasing only by 0.2cm. Group M grew by 0.7cm, and having an average height of 2.9cm on Day 5.
Ok, I feel like a commentator now... >.<
