Hypotheses Experimental or Null Hypothesis IV & DV One-tailed & Two-Tailed

Aim: O A general statement about what the research intends to investigate O The research’s purpose Hypothesis: O Specific & precise statement about the outcome of research. O It is testable. O It states a prediction about the outcome of certain conditions. O It can be accepted or rejected to show the outcome.

Which of the 2 statements is an aim and which is an hypothesis? O Dr Young thinks that children who have a daytime nap will show better recall of images than children who do not have a daytime nap. O Dr Young is interested in investigating whether sleeping during the day affects learning in pre- school children.

Task O From the following hypotheses decide if it is an: 1. Experimental or Null Hypothesis 2. IV & DV 3. One-tailed or two-tailed hypothesis

O Time of Day affects alertness O Social class has no effect on IQ scores O Drug A increases anxiety O Bulls will charge more often when presented with a red rag than when presented with a blue rag
