Relationships: T-tests, statistics homework help

Each of the discussions in this area has one main nominal (or ordinal) variable – and the output from a number of t-tests with different interval variables.

Choose ONE of these sets of t-tests to discuss – Your first post should be interpreting one of these t-tests ( in attached file)

Write out the research hypothesis (name the variables and say they are related) and the null hypothesis (name the variables and say that they are not related).

  • Figure the df (total N-2) and, using an alpha of 0.05, find the critical value of t.( Scanned file)
  • Make a decision about the null hypothesis – accept or reject.
  • Interpret your findings – is there a relationship between these two variables? If so, what is the nature of that relationship? (Refer to the means…) Speculate on why these findings might be as they are.
  • Nominal/Ordinal (Independent) variables: Sex/Gender or Pet

    Interval (Dependent) variables: Classes, or The number of times one eats per day, or Entertainment $ per week, or Height, or Work hours, or Study hours
