GED® Science Prep: Data Analysis Example Problem

You are sure to see some data analysis on your GED® science test. That can take a lot of forms. In this question of the day it's graph reading combined with percentages. Follow along as Kate walks you through this tricky little data analysis problem.

You would be a great Math teacher👍🏻. Love the way you explained how to get the answer and to empathize how it’s important to read the subject title. Thank you for the video.

She is a great teacher 💖 I feel lucky to find her.

Welcome!

[@Kimberlygreen2271]

This was great! thank you for breaking this down for me so I could understand this in detail....

[@LightandSaltLearning]

Yay!

[@TheLightBeatsDarkEvrytm]

Another good one. Thank you!

My pleasure!

[@alohabraztravel6259]

You are brilliant!

You must be from Hawai'i, eh, @Alohabraztravel? I am too! Grew up in central O'ahu.

There are a number of similar problems on the math exam. Somehow I got the idea "of" is divide? Thank goodness you write out the 8.7 million, I get so confused with moving the decimal when not doing that.

[@LightandSaltLearning]

It's a very common error to think "of" means divide. I think it's because of that thing we were talking about the other day, how students often mistakenly assume that multiplication always makes things bigger and division always makes thing smaller.
When we are using "of" to mean multiply, we are almost always SCALING THINGS to a smaller size.
For example, "half of 20" is actually 1/2(20). But because so many students do the same problem by dividing by 2 instead of multiplying by 1/2 (which will give the same result of course), they think, well, it must mean divide.
Does that make sense?

Wonderful 👍🏻👍🏻

[@LightandSaltLearning]

Glad you enjoyed the vid!

[@johnpaiva4581]

I wish I was in your class.

[@LightandSaltLearning]

That's the beauty of UA-cam, I think! I can have students in "my class" from all over the world.

[@sabinaslmn36]

Thanks give some more examples

[@LightandSaltLearning]

I have a ton of examples of these types of skills. Check out my science playlist

[@KENELENOFFICIAL]

You didn’t even need to do all that .its obvious it would have to be the least amount out of the questions because it s 7^

[@meganrobb9353]

Yea..but i think she is explaining it so students know how to work out a problem like this:)

[@latonyahall2086]

I got a 139 on my ged ready

[@LightandSaltLearning]

Gotcha. Tell me about the way youve been studying. What resources? How often? etc.

@@LightandSaltLearning I Am Studying through you tube and Kaplan books but I had a problem with independent and dependent variables

@@latonyahall2086 Yes, a lot of students struggle with that. Here are some vids ua-cam.com/video/syIWwtrg1pw/v-deo.html ua-cam.com/video/Swa9jpXGX0U/v-deo.html ua-cam.com/video/Oz4bKiZDREA/v-deo.html ua-cam.com/video/KkRKFjgWlUo/v-deo.html
