hypotheses

• what is a hypotheses

  a precise and testable statement about the world
• what are the different types of hypotheses

  experimental/alternate hypotheses

  null hypotheses
• what is the experimental/ alternate hypotheses

  there WILL be a difference in the DV between the Iv conditions
• what is the null hypotheses

  there WON'T be a difference in the DV between the IV conditions
• what are the two types of experimental/alternate hypotheses

  directional (1 tailed)

  non directional (2 tailed)
• what is a directional hypotheses

  states that the kind of difference or relationship between two conditions or two groups of participants
• what is a non-directional hypotheses

  simply predicts that there will be a difference or relationship between two conditions or two groups of participants BUT DOESN'T SAY WHICH WAY
• what is the formula for writing directional alternate hypotheses

  IV Condition A will perform better/quicker than IV Condition B

  OR

  IV Condition B will perform worse/slower than IV Condition A
• what is the formula for writing non- directional alternate hypotheses

  There will be a statistically significant difference in Dv between IV Condition A and IV Condition B
• what is the formula for writing a null hypotheses

  there will be no statistically significant difference in the DV between IV Condition A and Iv Condition B. Any differences found will be due to chance
