Part 1: Sample Methodology
When writing about the methodology, a researcher needs to identify the key components of the study as described in Week 5 lecture on Sampling.
In probability sampling, as the size of sample as a proportion of the population decreases, so does the probability of selection. The larger the sample size, the more precise the estimates are. If a sample has a sample size of 1000 cases, the margin of error or sampling error.
A. Yes
B. No
Accepted characters: numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5000), ''E" or "e'' (used in scientific notation). NOTE: For scientific notation, a period Iv1UST be used as the decimal point marker.
When your measurement error is between 4.5 and 5%, the number of cases are _ . Enter a number (not text).
Tip: Use your Lecture 5 slides.
