ohn and Susan are discussing the various audit sampling techniques available to auditing firms after their auditing class one day. John nentions to Susan that he heard the auditing professor discussing standard deviation and sample size as part of classical variables ampling and was confused as he always thought standard deviation had more to do with statistics than auditing. John asks Susan if he understood what the professor was referring to, and if there is any connection to classical variables sampling. Which of the ollowing would be Susan's best response to this question? Classical variables sampling is one of the many audit sampling options available to auditing firms undertaking an attestation engagement. There is an inverse relationship between standard deviation and sample size, in that when estimated standard deviation is lower, sample size should be higher. Classical variables sampling is one of a large number of audit sampling options available to auditing firms. If an auditor is using classical variables sampling, then a direct relationship exists between estimated standard deviation and sample size, in that the larger the expected standard deviation, the larger the sample size, and vice-versa. There is a relationship between classical variables sampling and audit sample size. If more variables are to be sampled as part of the audit, then sample size is typically assessed as higher. Standard deviation refers to where the average point in the sample will lie, and how far it may deviate from the population average. None of the choices is correct
