1 Statistical Literacy In a statistical study what is the difference between an individual and a variable? 2. 1 Statistical Literacy Are data at the nominal level of measurement quantitative or qualitative? 3. 1 Statistical Literacy What is the difference between a parameter and a statistic? 4. Statistical Literacy For a set population, does a parameter ever change? If there are three different samples of the same size from a set population, is it possible to get three different values for the same statistic?

Answer #1

1.

An individual is a member of the population of interest. A variable is an aspect of an individual subject or object being measured.

2.

Qualitative

3.

A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample.

4.

Never

5.

Data from samples may vary from sample to sample, and so corresponding sample statistics may vary from sample to sample.

A controversial study was recently written in a New York newspaper.  The study estimated the difference in salary between male and female lawyers in New York. They collected some large random sample data and constructed a 99% confidence interval estimate of the difference between mean average hourly pay for male lawyers and for female lawyers.  Male hourly pay was population 1 and female hourly pay was population 2 (male pay – female pay).  Assume the samples met all the assumptions for inference.   (-$91.48,...

This project is related to statistical inference about the difference between two population parameters and the analysis of variance. You need to formulate hypotheses testing and confidence estimation as you learned in class. Each group must collect data related to the topic of their choice. You should specify your parameter of interest and the claim, make the hypotheses, perform test calculations and estimation, and make a conclusion. specify your parameter of interest and the claim, make the hypotheses, perform test...

11 . Choosing the appropriate test statistic You are interested in the difference between two population means. Both populations are normally distributed, and the population variances σ212 and σ222 are known. You use an independent samples experiment to provide the data for your study. What is the appropriate test statistic? F = √[2/n1 + 2/n2] F = s1/s2 z = (x̄1 – x̄2) / √[σ2/n1 + σ2/n2] z = (p̂1 – p̂2) / √[p̂(1 – p̂)(1/n1 + 1/n2)] Suppose instead...
