In Problems 3 and 4, (a) identify the shape of the distribution and (b) determine the five-number summary. Assume that each number in the five-number summary is an integer.
Step 1 of 5) In Problems 3 and 4, (a) identify the shape of the distribution and (b) determine the five-number summary. Assume that each number in the five-number summary is an integer. In addition, the explanatory variable is not manipulated. Designed experiments are used when control of the individuals in the study is desired to isolate the effect of a certain treatment on a response variable. We introduced five sampling methods: simple random sampling, stratified sampling, systematic sampling, cluster sampling, and convenience sampling. All the sampling methods, except for convenience sampling, allow for unbiased statistical inference to be made. Convenience sampling typically leads to an unrepresentative sample and biased results.
