Research And Design

  1. What is a correlation coefficient?
    • It is a relationship that exists between two variables.
    • Describes the strength and direction of the two variables.
  2. What is the Spearmans RHOS?
    Used with non-parametric data


    • The Spearman procedure examines the difference between the two sets of
    • rankings for each participant.

    • The rs calculated value is given with a
    • corresponding p value.
  3. What are the five levels of evidence?
    • 1. Systematic review
    • 2. RCT
    • 3. quais expriemental, prepost, cohort, case control
    • 4. Correlational studies of multiple sites
    • 5. correlational studies, descriptive studies, qualitative studies, experiemental.
  4. What are the Two types of Descriptve Research?
    • Univariate: A single variable
    • Co variate: relationships between Variables
  5. WHAT IS PROBABILITY SAMPLING?
    Simple random sampling

    • Unbiased, use table of random
    • numbers, participants are labelled

    • lRandom drawing of numbers from a
    • hat.

    2. Systematic sampling

    • l1:10 beginning from a random
    • position on a selected named list. E.g. Every 10th person on a list. Starting
    • point is random. Similar to random sampling if no order to the listing.
