Lecture 02 Statistics Draft Download Free Pdf Probability Lecture 02 free download as pdf file (.pdf), text file (.txt) or view presentation slides online. this lecture covers data collection methods in statistics, distinguishing between primary and secondary data, as well as structured and unstructured data. Determine what is the population of interest, the sampled population, the sample, the population parameter and the sample statistic in the following example. a candidate for galesburg mayor wants to determine what percentage of knox college students will support them in the upcoming election.
Types Of Sampling Lecture Notes Pdf Sampling Statistics Sampling involves the collection of data on smaller number of units in comparison to complete enumeration, so the cost involved in the collection of information is reduced. additional information can be obtained at little cost in comparison to conducting another survey. From the sample of 8 colleges and universities, determine the proportion that are located in the midwest. Other sampling distributions we have been looking at the relationship between ion (p), the population standard deviation (σ), the population median, in each case we use a statistic from a sample to estimate the parameter. each of these statistics has its own sampling distribution. Compute the sample mean and variance. use this sample mean and variance to make inferences and test hypothesis about the population mean.
Lecture 9 Pdf Probability Sampling Statistics Other sampling distributions we have been looking at the relationship between ion (p), the population standard deviation (σ), the population median, in each case we use a statistic from a sample to estimate the parameter. each of these statistics has its own sampling distribution. Compute the sample mean and variance. use this sample mean and variance to make inferences and test hypothesis about the population mean. Visualize and interpret sampling distribution — simulate and plot the sampling distributions of sample proportions. analyze the shape, center, and variability of sampling distributions for sample proportions. understand how increasing or decreasing sample size may affect key features of the sampling distribution such as shape, center, and. Chapter learning objectives explain how descriptive statistics can make data understandable construct and analyze frequency distributions for variables at each of the three levels of measurement compute and interpret percentages, proportions, ratios, rates, and percentage change analyze bar and pie charts, histograms, and line graphs. Each of the following topics has links to printable lecture notes and narrated lecture slideshows. "test your knowledge" problems are brief, quick checks to see if you understood the lecture material. Sample is a selected subset of a population. a parameter is a numerical quan tity calculated from a population, whereas a statistic is a numerical quantity calculated from a sample.
