A lot of people, including teachers, are saying it's a line graph. I'm pretty sure that's wrong, and that the teachers would have to see the question and read it all to formulate a correct answer.
It can't be a line graph because the dude was counting the number of areas that had a reaction in them. Every minute, he opened the dishes, and checked. If there was a reaction in that area, he counted it. If not, he replaced the filter paper and left it for another minute.
There was a total of 100 areas. They either reacted, or they did not. He doesn't take the size of the reaction into consideration. Doing a line graph implies that, at 2.5 minutes for example, it would indicate 32.3 "number of areas" on your graph. Which is impossible because he is counting in integers.
Your thoughts?
nope, thats wrong. it was a line graph, as they didnt mention in the question "bar or histogram" and they also said that "plot the points" plot; therefore its a line.She7taman said:It wasn't that hard. But did you guys draw the graph as a line graph or as a bar chart?

honestly what u said is so convincing bas i think that most of the candidates including me drew a line graph so they should accept itShe7taman said:ynateil said:nope, thats wrong. it was a line graph, as they didnt mention in the question "bar or histogram" and they also said that "plot the points" plot; therefore its a line.
Are you serious? "Plot a graph" applies to all kinds of graph. I've seen it countless times in exams where the question said "plot" and the in mark scheme the correct answer was a bar or histogram.
Secondly, a line graph wouldn't make any sense. There can never be a half an area. He doesn't count half areas. At 1 minute, it was say, 18 areas. At 2 minutes, it was 10. Your line graph would imply that at 1.5 minutes it may have been 12.6 areas. This is impossible. It's either an area had a reaction in it, or it didn't. There's no intermediate, hence, bar graph.
I'm pretty sure you're wrong on that account.

That would apply only if you were plotting results for the third column, representing the TOTAL number, but that wasn't what you were asked to do.lolostar95 said:BTW yes it could be a line graph let me tell u why .... because the area is not going to chage suddenly at once .... onethird of it then half then alll so this will be a line graph

Again, you are wrong. If the experiment had been at 0.5 minute intervals, and if it was 18 at 1 min and 10 at 2 min, if he checks at 1.5 minute, he will *never* find a fraction. He may find a small area and a large area, but again, he will count those as 2.
There can never be any fractions in this design. He is counting the number of new areas that appeared. There can never be half an area, no matter its size. So the guy running the experiment doesn't care if one third of the circle changed, he's going to count that as one.
So to answer your question, yes, it will change suddenly from the point of view of the experimenter. There is no intermediate. There can never be.
Also, Divalicious has it right.

Divalicious said:Yep...
Too bad all my colleagues are still arguing with me, saying it's supposed to be a line graph, and I can't seem to convince them :shock:
And I bet they'll just go to teachers, and just explain the question in a vague way, like 'how to plot results for enzymes activity?' and teachers would just say it's line graph -.-
BTW I did the same :lol:phro5031 said:lolostar95 said:ok now what was the similarity between the two freakin' drawings(the ginger and the lotus)
i wrote a stupid answer since it was a stupid question , i wrote they both have greyish inner body , hahahahahaha :lol: :lol:
see this question wasnt clear ..... I think that the bio and the esl examiner are brothers their mind is so different from the normal humanShe7taman said:Divalicious said:Yep...

That's exactly the case over here, with some teachers saying line graph because all the students told them was "enzymes". I do hope line graph is rejected, just so I can watch their pitiful arrogance smash against the wall of reality as their ignorance is vibrant in the debris.
Hehe. I feel TOTALLY the same!She7taman said:[
