Statistics 1 midterm exam
Search this site. Some practicals TP will be included, covering R language programming and applications to the bootstrap and Monte Carlo methodologies. Purpose Sitemap. Purpose This course is the first part of the L3 statistics course, the second part being devoted to tests and model choice, taught by Marc Hoffmann.
It covers the fundamentals of parametric statistics, both from mathematical and methodological points of view. With some forays into computational statistics. The main theme is that modelling is an inherent part of the statistical practice, rather than an antecedent to the statistical step. Data may be a given, while models almost never are. This means one should keep a critical eye about models and develop critical tools to assess their adequation.
Including, first and foremost, an assessment by simulation Monte Carlo methods. As you may have noticed, the course is entirely in English, except for the partial and final exams. This means the practicals TD are in English as well and students are expected to communicate in English. There is indeed at least one course taught in English in each semester of the L3 and M1 years: Statistics 1 is the chosen course for the first semester of L3.

Have a good summer and thanks for all your hard work this semester. All homework is due at the beginning of class on Tuesday.
Thus, homework assigned on Tuesday and Thursday is due at the beginning of class on the following Tuesday. Additional Problem for 2. Include both of the histograms in your HW. Then write a paragraph discussing the differences between the male and female heights that you can see from the histograms ie.
Do either of the histograms have a distribution that is approximately normal? HINTS: If you are having trouble getting the book data, see the R intro lecture or look at the back of the quick reference sheet. See the top part of this page to download the data sets. The time vector t goes from to Homework: If you need more explanation and practice with summation notation: see this page.
You can find the second set of differences in the same way once you figure out the correct column name.
To find the post pennies use the same method but take a look at the Coins table to see what they are called and then modify the above statement. Additional problem: Use the following code to make two boxplots for comparing gender against bear weight and length.
Then use the boxplots to discuss and compare the distribution of lengths and weights of bears in terms of their gender. Make sure the book data is loaded into R first. Lecture: Handout Printout next lecture on counting, we may cover part of that if we have time. Lecture: Handout AHandout B. Sec 6. You must make sketches to show the area. For example, to do 6. In R you would type:. Sampling distributions, estimators, and the Central limit theorem CLT. Section 6. However, if the book asks you to find the test statistic, find that using the equation.
Hint for See the section on p-value in the notes, it also discusses what to do. Note 1: You do not need to find the test statistic or critical values. We are using the p-values. Note 2: R uses the continuity correction for more accurate p-values. To find the post quarters use the same method but take a look at the Coins table to see what they are called and then modify the above statement.
The command summary Coins is helpful to find the categories. Include scatter plots with regression line and residual plots. Hint for 5 and 7: you will need to determine if the linear correlation coefficient is significant.This AP Statistics Midterm Exam has 22 problems several with multiple responses required covering the following topics:.

Giving the mean number of meters a guided missile lands from the target but not the variability. Giving the mean amount of IQ increase seen in children in a single year but not the variability. Giving the mean number of crimes committed by a demographic but not the variability. The lower the number of participants, the more the -1 increases sample variability.
Standard deviation is less susceptible to outlier scores than the variance. Standard deviation takes into account degrees of freedom of the sample. Which of the following is not a requirement of a perfect normal distribution? Which of the following is not true of standard normal distributions?
