Examples: Sample: A (smaller) subset of individuals chosen from the population In statistical inference, we use sample data (the values of the variables for the sampled individuals) to make some conclusion (e.g., an estimate or prediction) about the population.

Examples: • Typically a parameter cannot be calculated from sample data. • A statistic is a function of random variables. • Given the data, we can calculate the value of a statistic. Examples of statistics: Order Statistics • The k-th order statistic for a sample X1, X2, …, Xn is denoted X(k) and is the k-th smallest value in the sample.

We use data and statistics to estimate these parameters, which is known as inference. Let’s take slide 4, and consider each model one at a time. First, let’s see how we represent spatial data. Here is some notation often used in spatial statistics. The 3 most common types of spatial data. Examples of geostatistical data.

Typically, this exposure begins with a non-calculus-based introductory course that would expand the empirical view of statistical inference found in this high school progression to a more general view based on mathematical formulations of inference procedures. (The Advanced Placement Statistics course is at this level.)

* Describe your inference procedure; show your calculation; results: PHANTpMS? PANIC? * Computer(?) results (using minitab output, we will go to the computer lab together to do this) * Make conclusion(s), discuss confidence and doubts about results, using a conf level, p-value, and/or ? My brain is empty. Help give me some ideas.

inferential statistics. Statistical inference uses probability to determine how confident we can be that the conclusions are correct. Effective interpretation of data (inference) is based on good procedures for producing data and thoughtful examination of the data.

Statistics is everywhere in today’s society. You do not go a single day without hearing about some study and/or conclusions from a study or an experiment. AP Statistics is designed to be an interactive, thought provoking course which allows you to construct your own understanding of concepts and techniques of statistics.

statistical inference. is an estimate, prediction, or some other generalization about a population based on information contained in a sample. Following examples are for checking “Popluation, variable, sample, and Inference ” Please look at Example 1.1.(Page 9 in our Textbook) Please look at Example 1.2.(Page 9 in our Textbook)

Chapter 11 - Continued Inferential Statistics (The logic of inferential statistics) Probability is a predicted occurrence such as 5 in 100 times (5% or .05) In previous example, the probability of the population mean being outside the 95% CI (of 81.08 to 88.92) is 5%

The formal inference is used to answer the investigative question. An understanding of sampling variability may be implied in the use of the bootstrapping process. The examples above are indicative of the evidence that is required. The student uses statistical methods to make a formal inference, with justification.
