S-IC.1

[tomergal]

Could you please elaborate on the differences between this standard (S-IC.1) and the 7th grade standard 7.SP.1?

(7.SP.1: “Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.”)

[Bill McCallum]

Partly it is just a matter of the level of sophistication with which the topic is treated. But notice also that the high school standard makes explicit reference to population parameters, whereas the Grade 7 standard simply talks about gaining information about the population. So in Grade 7 you might just look at a graphical representation of the sample and discuss what you can infer from it, whereas in high school you get more into the technical details of estimating parameters such as mean and standard deviation.
