EDCO 735 / EDCO735 QUIZ 2 N decreases the sampling distribution gets: - wider more pointy more leptokurtic more representative Warner - Section 2.11 Calculating the sample... standard deviation always makes use of: variance random sample convenience sample nominal level of measurement In order to calculate the mean you must: divide by the sample size have at least ratio level of measurement have a normal distribution use a representative sample A two-tailed outlier for the t distribution must have a t score equivalent to the: highest 2.5% or lowest 2.5% of the t distribution highest 5% or lowest 5% of the t distribution only the highest 5% of the t distribution only the lowest 5% of the t distribution Question 5 0 / 3 pts Sampling error refers to: - about how much we should expect our sample mean to be from the population mean about how much we should expect an individual score in our sample to be from the population mean the amount of error in our measurement how representative our sample is Warner - Section 2.10-2.14 As N decreases we can expect the standard error of the mean to: - increase decrease neither increase nor decrease either increase or decrease Warner - Section 2.10 In order to calculate the sum of squared deviations you must: calculate the mean divide by degrees of freedom take the square root of the sum multiply each score by itself The standard error of the mean is conceptually similar to: the standard deviation variance sum of squared deviations causal inference The standard error is related to all of the following except: - causal inference dependent on sample size is smaller with a larger sample involves the confidence interval Warner - Section 2.11 As N increases, the standard error of the mean: - decreases increases remains constant varies randomly Warner - Section 2.12 Quiz Score: 15 out of 30 [Show More]
