BUS 308 Week 1 DQ 1 Language
  • For more course tutorials visit www.uophelp.com
  • Discussion 1-1/Language
  • Numbers and measurements are the language of
    business.
  • Organizations look at results in many ways
    expenses, quality levels, efficiencies, time,
    costs, etc. What measures does your department
    keep track of?
  • Are they descriptive or inferential data, and
    what i

BUS 308 Week 1 DQ 2 Probability

  • Things vary in life virtually nothing (except
    physical standards such as the speed of light) we
    interact with is constant over time.
  • Much of this variation follows somewhat

    Measurement issues. Data, even numerically code
    variables, can be one of 4 levels nominal,
    ordinal, interval, or ratio. It is important to
    identify which leve

  • 1. Question Data on the city from
    which members of a board of directors come
    represent interval data.
  • 2. Question Inferential
    statistics infer the characteristics of samples.
  • 3. Question The mode is which of
    the following?

BUS 308 Week 2 DQ 1 Hypotheses
  • For more course tutorials visit www.uophelp.com
  • Discussion 2-1/Hypotheses
  • What is a hypothesis test? Why do we need to use
    them to make decisions about relating sample
    results to the population
  • why cant we just make our decisions by the

BUS 308 Week 2 DQ 2 Variation
  • For more course tutorials visit www.uophelp.com
  • Variation exists in virtually all parts of our
    lives.
  • We often see variation in results in what we
    spend (utility costs each month, food costs,
    business supplies, etc.).
  • Consider the measures and data you use (in either
    your p

  • . Question How is the sum of
    squares unlike either the standard deviation or
    the variance?
  • 2. Question If sums of squares
    statistics are calculated for shoppers at three
    different retail outlets, what statistic will
    indicate the variability among those at each
    outlet?

BUS 308 Week 3 DQ 1 ANOVA
  • For more course tutorials visit www.uophelp.com
  • In many ways, comparing multiple sample means is
    simply an extension of what we covered last week.
  • Just as we had 3 versions of the t-test (1
    sample, 2 sample (with and without equal
    variance), and paired
  • we have several versions of ANOVA single
    factor, factorial (called 2-factor with
    replication in Excel), and within-

BUS 308 Week 3 DQ 2 Effect Size
  • For more course tutorials visit www.uophelp.com
  • Several statistical tests have a way to measure
    effect size. What is this, and when might you
    want to use it in looking at results from these
    tests on job related data?

BUS 308 Week 4 DQ 1 Confidence Intervals
  • For more course tutorials visit www.uophelp.com
  • Discussion 4-1/Confidence Intervals
  • Many people do not like or trust single point
    estimates for things they need measured.
  • Looking back at the data examples you have

BUS 308 Week 4 DQ 2 Chi-Square Tests
  • For more course tutorials visit www.uophelp.com
  • Discussion 4-2/Chi-Square Tests
  • Chi-square tests are great to show if
    distributions differ or if two variables interact
    in producing outcomes.
  • What are some examples of variables that you
    might want to check using the chi-square tests?
    What would these results tell you?

    hypothesis states that the sample data does not
    match an expected distribution.

    in the Chi-square test means the population
    distribution (expected) is not the source of the
    sample (observed) data.

  • At times we can generate a regression equation to
    explain outcomes.
  • For example, an employees salary can often be
    explained by their pay grade, appraisal rating,
    education level, etc.
  • What variables might explain or predict an out

BUS 308 Week 5 Final Paper (2 Papers)
  • For more course tutorials visit www.uophelp.com
  • The final paper provides you with an opportunity
    to integrate and reflect on what you have learned
    during the class.
  • The question to address is What have you
    learned about statistics? In developing your
    responses, consider at a minimum and discuss
    the application of each of the course elements in
    analyzing and making decisions about data (counts
    and/o
