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? 90s there are how many 95s and how many hundreds so this right over here has the same data as this list of numbers? It's just another way of looking at it and once you have your data arranged in any of these ways We can start to ask Interesting questions we can ask ourselves things like well. What is the range of data?
