Week SixHomework Exercise Answer thefollowing questions, covering material from Ch. 12 of Methods in Behavioral Research:Define the following terms:Descriptive statisticsScales of measurementMeasures of central tendencyFrequency distributionsCorrelation coefficientEffect sizeMultiple regressionHow are group means, percentages, andcorrelations used to describe research results?How can graphs be used to describe and summarizedata?A researcher is studying reading rates inmilliseconds per syllable. What scale of measurementnominal, ordinal,interval, or ratiois time in milliseconds? Explain your response.Under what circumstances is the median or mode abetter measure of central tendency than the mean? Explain your response.True or false: The standard deviation and therange are sensitive to outliers. Explain your response.True or false: The standard deviation can neverbe 0. Explain your response.A researcher is investigating the effects of anxietyon creativity. Individuals with varying levels of anxiety are asked to completea measure of creativity. The results show a classic U-shaped distribution; thatis, individuals with moderate levels of anxiety score the highest on tests ofcreativity. Individuals with very low or very high levels of anxiety score muchlower on tests of creativity. What would be a good statistic to use in thiscase? Explain your response.What are some applications of multipleregression models (equations / techniques)? Provide an example.Explain how and why multiple correlations areused as prediction variables?
