PSY201H5 Lecture Notes - Lecture 2: Decimal Mark
Document Summary
Designing an experiment: single group design: the group is usually a population of individuals, need to define how the attribute will be measured. Interested in an attribute, characteristic, or behaviour of members of the group: for example: iq tests are used to measure intelligence. To find out, construct a frequency histogram: how you analyze data depends on population distribution, this can be only done by constructing a histogram. Measurement precision: suppose we measure heart rate to the nearest 10th of a beat per second (95. 4,103. 2,etc. , our measures are carried out to 1 digit to the right of the decimal point, measurement precision = 1. Measurement precision: suppose we measure heart rate to the nearest 100th of a beat per second (95. 43,103. 29,etc. , our measures are carried out to 2 digits to the right of the decimal point, measurement precision = 2.
