Question

Chapter 1 Assessment For problems 1 – 5, determine the level of measurement (nominal, ordinal, interval, ratio) for each of the variables listed. Please note: each level of measurement may be used more than once, or not at all. 1. (1 point) Names of patients visiting a walk-in clinic 2. (1 point) The severity of the patient’s pain level (low, moderate, high) 3. (1 point) The patient’s annual household income, in U.S. dollars 4. (1 point) The patient’s weight, in pounds 5. (1 point) The Patient’s gender identity (male, female, other) For the scenarios below, determine which sampling method was used (simple random, cluster, convenience, stratified, systematic), and briefly state how you were able to identify the type of sampling being used. Please note: each sampling method will be used only once. 6. (2 points) A sample of customers was created by surveying all customers in the store on Monday morning 7. (2 points) A sample of customers was created by randomly selecting 50 customers using their account numbers (each customer has a unique account number) 8. (2 points) A sample of customers was created by dividing the customers up into groups based on the length of time they have shopped at the store, randomly selecting two of these groups, and contacting all customers in the selected groups 9. (2 points) A sample of customers was created by selecting every 5th customer through the door, beginning at a randomly selected start time 10. (2 points) A sample of customers was created by dividing customers up by income level, and randomly selecting 20 customers from each income level

Answer 1

1) Names of patients visiting a walk-in clinic - Nominal

2) The severity of the patient’s pain level - Ordinal

3) The patient’s annual household income, in U.S. dollars - Ratio

4) The patient’s weight, in pounds - interval

5) The Patient’s gender identity - Ordinal

6) Convenience sampling here the approach used is non probabilistic.

7) It is Random sampling where the sample is selected by randomly selecting the customer.

8) Cluster sampling, The customers made into groups and randomly selecting groups.

9) Systematic sampling systematically collecting every 5th customer.

10) Stratified sampling The customers made into groups and randomly selecting a customer from each group..
