Today Aiden and started in the content of Statistics and the idea of studying data. We discussed definitions of populations and samples. Then we discussed what makes a sample a good representation of the entire population. We considered the idea of a town considering whether or not they should build a new stadium. Aiden and I agreed that if we only surveyed people coming out of a sports store, the data could be skewed. By looking at a few experiment types, we could see that the more random the sample collected is, the more likely it would be representative of the entire population. We practiced studying a data set of 138 students and then studying a random selection of 20 students. We compared 3 trials to see that though they were all different data sets, they were all fairly collected and seemed to be a good representation of the entire 7th grade population. We also made inferences about the data we saw, considering that inferences may not be 100% correct but just the information we can take away from sampling an entire population.
