A class of 25 students learns the material using the first method and then using the second method. This experiment uses a(an) ______ research design, which could have been improved by using a ______. a) between groups; single blind procedure b) mixed; a double blind procedure c) mixed; counterbalancing d) within groups; counterbalancing 15) Before commencing an experiment on children, the experimenter is ethically required to collect informed consent from a) the children. b) a parent/guardian. c) the children and their teachers. d) the children and their parent/guardian. 16) Withdrawal rights means a) participants are permitted to withdraw from illicit drugs during the experiment b) participants must not withdraw from the experiment until it is finished c) participants are permitted to withdraw from an experiment at any time d) the experimenter can withdraw participants from favourable conditions 17) An independent variable is a) anything that may affect the DV b) the thing an experimenter measures in research c) the thing an experimenter manipulates or changes in research d) something that can affect the DV that was not controlled for 18) The dependent variable is a) the thing being measured b) the thing being manipulated c) the thing we control for d) the thing we depend upon 19) Ava wants to test if drinking coffee can effect short term memory. The IV would be a) short term memory b) scores on a memory test c) the amount of coffee drunk d) the time since coffee was consumed 20) Jesse wants to find out if VCE study scores can be improved by students getting at least 8 hours sleep a night.
