There is a review worksheet over the standard normal distribution in the Handouts folder linked on the right side of the blog. I have also posted solutions to the Probability and Counting review in this folder.
The website fivethirtyeight.com uses a lot of data and publishes articles about their findings. Visit the site and in the comments describe what you found there. How does it relate to the statistics we discussed in class?
Challenge Problem (Due Tuesday, March 6): The website fivethirtyeight.com deals with a lot of data and publishes articles on their findings. Visit the page https://data.fivethirtyeight.com and choose a data set and article to look at. Read the article. How do they use the data in the data set? Download the data (you may need to right-click to download) and try computing some statistics with it.
In high school I took statistic and we used the math is fun website. They helped me out a lot through the whole time in class.
ReplyDeleteWhat parts of the math is fun website did you use? What did you find most useful?
DeleteWhen I went to this site I clicked on the "How popular is Donald Trump" and in this data set they used sample sizes like we did in class and they showed the percentage of people who approved and disprove of him. Also near the bottom of the page they compared his approval rating to the past presidents.
ReplyDeleteIn the article at the bottom of the page, Julia Azari argues presidential ratings are flawed for several reasons but I think the most interesting facet is political preference. Focused research suggests that, "political preferences play a role in just about any expert rankings," and "the more someone pays attention to politics, the more entrenched and polarized their views."
DeleteThey're saying those that are filling out the surveys are likely subject to partisan leanings. I think this article highlights the importance of gathering information from multiple sources before concluding facts. I wonder if this means the margin of error can be bias as well?
Wesson, that's a good question. The margin of error ignores all types of errors except the sample-to-sample variation due to choosing the sample randomly. What this means is that the margin of error doesn't cover errors due to poor sampling methods, bias in choosing the sample or issues like nonresponse. These difficulties can be more serious than random sampling error, but need to be accounted for in a different measure than the margin of error.
DeleteI've never used this math is fun website. It was kind of interesting. I was able to understand it a little better. This website as a whole helps me a lot with the work.
ReplyDeleteOn fivethirtyeight.com I found a variety of articles and prediction percentages for basketball games. I also saw polls and predictions for subjects such as health and science and economics. This relates to the problems we did in class about sports players for example height and weights of players. There were also links on all articles about similar subjects. -Kyle Ballard
ReplyDeleteOn the Fivethirtyeight website, I read up on Why Does Everyone Hate The Media? With this passage the information takes statistics into the realm of the histograms. With this example I see how this topic in math can be useful other than in the classroom.
ReplyDeleteAfter following the link to the website, Fivethirtyeight.com, I sort of browsed between the different articles. I then came across an article titled 'When Does Praying In Public Make Others Uncomfortable? '. Upon reading this article, it discussed how Christians and Atheist feel about certain things being done while out in public. There was then a two surveys that were given to a total of 661 people and from there, results were then taken. These actually made me think about the methods that we have used in class.

I read the article "Is Uber Making NYC rush hour worse? In this article a study was done to see if Uber was making congestion worse at some times. There was two surveys taken, and the results showed Uber isn't making rush hour any worse and any increase it generates in overall traffic is minimal. This showed me histographs and statistics are used in real life situations all the time.
ReplyDeleteI also read the article "Here's what your part of America eats on Thanksgiving" This article is all about who eats what on Thanksgiving. This survey had 1,058 repondants, and turkey was the winner with 82%. I learned you are able to use statistics to figure out the answer to questions as simple as what people prefer on Thanksgiving.
ReplyDeleteI read the article "2017-2018 NBA predictions". In this article it displays a chart with all of the NBA teams projected records, their chance of making the playoffs, chance of making it to the Finals, and their chance of winning the finals. This chart displays an actual representation on what a basketball fan would look for when wanting to know an expected outcome of the 2017-2018 NBA Season and gives an estimated guess on who they think will come out on top and where each team will finish that year.
