Null 2 of 26 A hypothesis that states that results are not due to chance and that they are significant in terms of supporting the idea being investigated. Research Hypothesis 3 of 26 One tailed hypothesis Directional 4 of 26 A hypothesis where the direction of the results is not predicted. Two-tailed 5 of 26 Everyone in the entire target population has an equal chance of being selected Random Sampling 6 of 26 Using people from the target population who are available at the time. Opportunistic Sampling 7 of 26 Selects subjects in a logical way. Systematic Sampling 8 of 26 Participants volunteer themselves. Self-selected Sample 9 of 26 Divides target population into groups. There are people in sample from each group in same proportions as population. Stratified Sampling 10 of 26 Alternating the order at which participants perform in different conditions of an experiment. Counterbalancing 11 of 26 Material for an experiment is presented in a random order. Randomisation 12 of 26 Participants don't know which control/design they are in. Single-Blind Design 13 of 26 Neither the participants or researchers know what condition the participants are in. Double-Blind Design 14 of 26 Observations are made at regular time intervals and coded. Time Sampling 15 of 26 Keeping a tally chart of each time a type of behaviour occurs. Event Sampling 16 of 26 Focuses on one individual for a set period of time. Point Sampling 17 of 26 Gathers data in numerical form and is concerned with making 'scientific' measurements. Analysis uses a barrage of inferential statistical tests. Quantitative Data 18 of 26 Gathers information that is not in numerical form such as feelings and emotions. Qualitative Data 19 of 26 All values in a set of data are added together and divided by the number of values. Arithmetic mean 20 of 26 When all values are arranged in order - the middle value. Median 21 of 26 The most frequent value or score in a set of data. Mode 22 of 26 Simple measure of dispersion - shows the total spread of data Range 23 of 26 When all values are arranged in order - the middle value. Median 24 of 26 The most frequent value or score in a set of data. Mode 25 of 26 Simple measure of dispersion - shows the total spread of data Range 26 of 26
