You have been told that for university classes, students are supposed to spend two hours working outside of class for each hour in class. You are curious to know the average amount of time students at your school spend working outside of class for each hour in class. You contact 100 students at your school and ask them, 'How many hours of schoolwork do you do outside of class for each hour in class?' The mean for the 100 responses is 1.2 hours.

a.) What is the population of interest, and what is the research question you want to answer about it?
b.) Explain in words what the population parameter is in this study, and identify the appropriate symbol for it.
c.) What is the value of the sample estimate in this study, and what symbol is used for it?

Measures of Central Tendency

This quiz evaluates the students understanding of the measures of central tendency seen in statistics. This quiz is specifically designed to incorporate the measures of central tendency as they relate to psychological research.

Terms and Definitions for Statistics

This quiz covers basic terms and definitions of statistics.

Know Your Statistical Concepts

Each question is a choice-summary multiple choice question that presents you with a statistical concept and then 4 numbered statements. You must decide which (if any) of the numbered statements is/are true as they relate to the statistical concept.

  • Point estimate and Interval Estimate of a Parameter

    A point estimate gives just a single value for the population parameter, which is the sample parameter. For example, the point estimate of the population mean is given by the sample mean.

  • Interval estimates and differences

    The best point estimate of the population mean m is the sample mean. The advantage of point estimate is that it is one specific number so easier to interpret and understand.

  • Questions from statistical inference

    b. the population parameter. c. a point estimate. d. the mean of the population ______ 3. The size of the standard error is affected by the standard deviation of the sample and a. a confidence interval. b. the population parameter.

  • Testing regression coefficients

    But since measuring the entire population is either not practical or too expensive, we collect a sample from the population and from that sample we calculate a sample statistic and use it to estimate the population parameter.

  • Construction of confidence intervals and proper interpretation

    In such cases, we make an estimate about the population parameters based on sample statistics. There are two types of estimates: point estimate and confidence interval.

  • Manager's sample of 25 delivery trucks. Confidence interval

    An appropriate use of confidence interval is to make an interval estimate (not pointed) of the population parameter. The sample mean is a point estimate for the population parameter.

  • Confidence interval

    Usually the best we can do is to select a sample from the population and estimate with a sample statistic called the sample mean (usually denoted by the symbol ).

  • Statistic Concepts: Estimates and Confidence

    It is desirable for a point estimate to be: (1) Consistent: The bigger the sample size, the more precise the estimate. (2) Unbiased: The expectation of the observed values of many samples equals the consequent population parameter.

  • Statistic Terms & Central Limit Theorem

    An estimator is defined as a function of the observable sample data that is used to estimate an unknown population parameter.

  • Parameter estimation: bias and variability

    To answer this it is important to realize that when we use a procedure to estimate a population parameter with a sample statistic, the value of the sample statistic would vary from sample to sample if we used the procedure repeatedly.
