I kind of liked it I didn't like it or they might have rated it on a scale of zero to five which would have been numbers But it's numbers that are measuring people's opinions as opposed to here We have numbers that are measuring their actual scores So there's all different types of data, and I don't want to get into all of that But let's just start thinking about different ways to represent this data So this is one way you could view this as a table where you have the name let me and then you have the score So you have your name column, and then you have your score column, and I could construct it as a table so clearly Looks like a table like that. That's one way one very common way of representing of representing data just like that That's actually how most traditional databases record data in the tables like this, but you could also do it in other ways so you could record it as a as a Oftentimes called a bar graph or sometimes a histogram So you could put score on The vertical axis here, and then you could have your names over here, and let's see the scores. Let's see maybe we'll make this a 50 actually let me just Mark them off, so this is 10 20 30 that's too big 10 20 30 40 50 60 70 80 90 so that's and then a hundred so that's a hundred one two three four five That would be 50 right over there, and then you could go person by person so Amy Amy record got a 90 on the exam so the bar will go up to 90 So that is Amy and then you have bill you got in 95 So it's going to be between 90 and 100 so it's going to be right over there Bill got a 95 And so it would look like this Bill So that is bill, and then you have cam who got a hundred on the exam so Make sure I'm hand drawing it So it's not as it's not as precise as if I were to do it on a computer So this right over there that is cams score Effort got the same score as cam so her score is going to be let me do that in the color in a first color That's a phrase score right now there. She also got a hundred so Efra Efra and then finally Farah got an 80 so 60 70 80 so Farah got Got an 80 so this is Farah score right over here, so this is another way of representing the data and Here we see it in visual form, but it has the same information you can look up someone's name And then figure out their score Amy scored a 90 bill scored a 95 cam scored 100 effort Also scored 100 Farah scored an 80 and there's even other ways you can have some of this information In fact sometimes you might not even know their names and so then it would be less information But it might just a list of scores the professor must say here are the five scores that were That people got on the exam and they were list 90 95 95 100 100 100 and 80 now if it was listed and if this was all of the data you got this would be less information than the data That's in this bar graph or this histogram And or the data that's given in this table right over here because here not only do we know the scores But we know who got what score here. We only know the list of scores But there's even other ways and I this is this isn't and this is not an exhaustive video of all of the different ways you Can represent data you could also represent data by looking at the frequency of scores? So the frequency of scores right over here, so instead of writing the people you could write the scores So let's see you could say this is 80 85 90 95 and 100 and then you could record the frequency that people got these scores So how many times do you have a score of an 80? Well Farah got a is the only person with the score of 80 so you put one data point there No one got an 85 one person got a 90 so you put a data point there one person got a 95 So you could put that data point right over there, and then two people got a hundred so this is one and two Let's see the other hundred is in this color So I'm just doing the color you wouldn't necessarily have to color code it like this So this is another way to represent, and this is you know in this axis you could just view This is the number so this tells you how many 80s there were how many?
