- 1The statistical analysis used for interval and ratio levels of measurement. Generally based on calculations using the mean.Parametric statistics
- 2The statistical analysis used for nominal and ordinal levels of measurement.non parametric statistics
- 3The general characteristic being measured on a set of objects, characteristics, or events, the numbers of which may take on different numerical values.Variable
- 4A variable with only two categories, such as gender.Dichotomous variable
- 5The four levels of measurement can be distinguished by these three characteristics/properties.Magnitude, Equal Intervals, Absolute zero point
- 6Eye colour, personality types, gender, car makes are all types of ............ level of measurement.Nominal
- 7Hotel ratings, Army Ranks, horse racing events are all types of .................. level of measurement.Ordinal
- 8Temperature, Time, performance rating on a scale of 1-10 are all types of ..................... level of measurement.Interval
- 9Weight, height, and performance rating on a scale of 0 -10 are all types of .................... level of measurement.Ratio
- 10A numerical index which attempts to summarise and descried a data set by identifying the most typical value in the data set.Measures of central tendency
- 11Another term for measures of central tendency because they attempt to describe a data set.Descriptive statistics
- 12The three common measures of central tendency.Mean, Median, Mode
- 13Arithmetic calculation of all the values in a data set.Mean
- 14Middle value of all the values in a data set.Median
- 15Value occurring most frequently in a data set.Mode
- 16Any value that is numerically distant from most of the other data points in a set of data, extreme values.Outliers
- 17The use of the mean should generally be used with ........... or ................. levels of measurement, or ................ variables.Interval, Ratio, Continuous
- 18The median is most appropriate with .......... level of measurement and should not be used with ........... DataOrdinal, Nominal
- 19The mode is used primarily to describe and summarise .................. data.Nominal
- 20Something which randomly contaminates the true score, which may be unknown.Random error
- 21Commonly used numerical indices of dispersion (variability).Range, Standard Deviation, Variance, Interquartile Range, Variation Ratio
- 22A theory about measurement that is expressed by the equation - X= T + E.True score theory
- 23Refers to an error which is not random but is a form of measurement error which systematically affects the measurement process.Systematic error
- 24The extent to which scores vary around the measure of central tendency.Variability
- 25The highest score minus the lowest score.Range
- 26What is meant by the abbreviation SD² or S²?Variance
- 27What is meant by the abbreviation SD or S?Standard Deviation
- 28A measure of variability associated with. The median measure of central tendency.Interquartile range
- 29A measure of variability which is associated with the mode measure of central tendency.The variation ratio
- 30Why do we use Standard deviation?To express the variability in terms of average deviations, that is how much on average do the scores vary
- 31The approach which refers to the empirical pursuit of objective knowledge derived through observation.The Scientific Approach
- 32What method follows this procedure? Observation, generalization, hypothesis, verification of hypothesis, proof or disproof, knowledge.The inductive method
- 33What method follows this procedure? Problems leading to new theory leading to testable statements and attempts to refute those statements using observation and experimentation.Deductive Method
- 34The most important aspect of a theory according to Thomas (1985).A theory must be open to falsifiability or refutability
- 35Which law states; "if we have to choose between two equally good theories we should choose the simpler more economical one"?The 'law of parsimony' or 'Occam's razor'
- 36What is a measure of variability which is associated with the median measure of central tendency? It involves identifying the value which would cut-off the first 25% of scores and the last 25% of scores.The interquartile range
- 37What is a measure of variability which is associated with the mode measure of central tendency?The variation ratio
- 38This provides a generalised Standard of Comparison, which allows one to compare and contrast the distributions on the same metric.Standardised Scores/Z Scores
- 39The foundation of the scientific approach.Empirical research
- 40the 3 requirements of a science areIdeas must of capable of being scientifically tested. Must be expressed in a clear and concise way. Observations need to be reliable.
- 41The main advantage of the scientific approachIt provides an objective set of rules and values for gathering and evaluating information and allows ideas to be tested, observed, and replicated
- 42Popper (1959) suggests that a more stringent and meaningful way to test a theory is by............Attempting to falsify the theory
- 43What should a good scientific theory reflect?The reality it is concerned with, what it is trying to explain
