• BUS 308 Week 1 DQ 2 Probability

• BUS 308 Week 1 Problem Set

• 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 predictable patterns
  that can be examined using probability.

• For assistance with these calculations, see the
  Recommended Resources for Week One. Measurement
  issues. Data, even numerically code variables,
  can be one of 4 levels nominal, ordinal,
  interval, or ratio. It is important to identify

• BUS 308 Week 2 DQ 1 Hypotheses

• BUS 308 Week 2 DQ 2 Variation

• 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 sample value?

• 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 personal or job
  activities).

  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?

• 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

  the data examples you have provided in the
  previous

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