Animal Genetics and Breeding Quiz 26 Quiz InstructionsThis quiz consists of 20 multiple-choice questions.You will be awarded 5 marks for each correct answer. Question 1: The measure of location which is the most likely to be influenced by extreme values in the data set is theRangeMedianModeMean Question 2: If two events are indipendent, thenThey must be mutually exclusiveThe sum of their probabilities must be equal to oneTheir intersection must be zeroNone of these alternatives is correct Question 3: μ is an example of a Population parameterSample statisticPopulation varianceMode Question 4: If a data set has an even number of observation, the medianCannot be determinedIs the average value of the two middle itemaMust be equal to the meanIs the average value of the two middle items when all items are arranged in ascending order Question 5: The sum of deviations of the individual data elements from their mean isAlways greater than zeroAlways less than zeroSometimes greater than and sometimes less than zero, depending on the data elementsalways equal to zero Question 6: The value that has half of the observations above it and half the observations below it is called theRangeMedianMeanMode Question 7: The most frequently occurring value of data set is called theRangeModeMeanMedian Question 8: A tabular summary of a set of data showing the fraction of the total number of items in several classes is a Frequency distributionRelative frequency distributionFrequencyCumulative Frei distribution Question 9: The standard deviation of a sample of 100 observations equals 64. the variance of the sample equals81064004096 Question 10: The measure of dispersion that is influenced most by extreme values isThe varianceThe standard deviationThe rangeThe interquartile range Question 11: The descriptive measure of dispersion that is based on the concept of a deviation about the mean isThe rangeThe interquartile rangeBoth A and BThe standard deviation Question 12: The ANOVA procedure is a statistical approach for determining whether or notThe means of two samples are equalThe means of two or more samples are equalThe means of more than two samples are equalThe means of two or more population are equal Question 13: Whenever using the t distribution in estimation we must assume thatThe sample size is at least 30The sampling distribution is approximately NormalThe population is approximately NormalThe finite population correlation factor is necessary Question 14: The known variable in regression analysis is calledIndependent variableDependent variableCorrected variableNone of the above Question 15: For comparing variability of two or more series we calculateStandard deviationCoefficient of variationStandard errorError variance Question 16: Two events are said to be independent whenOccurence of one affects otherOccurence of one does not affect otherBoth cannot happen simultaneouslyNone of the above Question 17: Which type of error is more dangerousType IType IIType IIIType IV Question 18: Given the N values in a series, the geometric mean isThe third root of the product of N valuesThe square root of the product of N valuesThe fourth root of the product of N valuesThe Nth root of the product of N value Question 19: Which of the measures growth here are based on every item of the series?RangeStandard deviationQuartile deviationAll of the above Question 20: A researcher selects a probability sample of 100 out of the total population. It isA cluster sampleA random sampleA systematic sampleA stratified sample
