Generating a Simple Random Sample
Generating a Simple Random Sample is a Grade 7 math skill from enVision, Mathematics, Grade 7, covering Use Sampling to Draw Inferences About Populations. To generate a simple random sample from a population of size for a sample of size : 1. Create a list of all members of the population. Explanation This procedure provides a structured method for creating a simple random sample. Assigning a unique number to every member of the population is crucial for ensuring that each one has an equal chance of being selected.
Key Concepts
To generate a simple random sample from a population of size $N$ for a sample of size $n$: 1. Create a list of all members of the population. 2. Assign a unique number to each member, from $1$ to $N$. 3. Use a random number generator to select $n$ unique numbers between $1$ and $N$. 4. The members of the population corresponding to the generated numbers form the sample.
