Answer:
Systematic Sampling
Step-by-step explanation:
Systematic sampling is a form of sampling in which the researcher applies probability sampling such that every member of the group is selected at regular intervals or periods. The researcher picks a random starting point and after an interval must have elapsed, another sample member is chosen. This sampling method is similar to that disclosed in the question because it has the key qualities.
For example, an interval is given after the 1000th soda is tested for quality. This means that the interval for testing can accommodate 1000 sodas after which the first member is tested again. So, this is a Systematic sampling method.

Step-by-step explanation:
If data are not normally distributed then there are only two tendencies for its distribution. It could either be skewed to right where most of the values are to the right of the mean.
Another tendency for the data is that they are skewed to the left. With this, most of the data are to the left of the mean.
Hence, the sample means also shifted depending on the skewness of the data.
