1) It is a) TRUE that the daily closing price of Tesco stock over the past month would be a time series.
A time series is a sequential measurement of the same variable, which the researcher collects over a period of time at regular intervals. As a list of observations, the ordering of a time series is important.
2) It is a) TRUE that the sample data that Ahmad collects from colleagues about their favorite places to visit is a cross-sectional data.
Cross-sectional data are experimental observations of many different individuals (subjects, objects) at a given time. It is the opposite of a longitudinal data, where there are multiple observations for each individual over time.
3) It is b) FALSE that a problem with convenience sampling is that the target population is not well-defined.
Convenience sampling occurs when the researcher relies on accessibility to determine the variables in the research sample instead of giving each variable a nonzero chance of participation.
Thus, a problem with convenience sampling is not the definition of the target population, but the target sample is not clearly defined.
4) It is a) TRUE that the closing price of a stock is an example of ratio data.
Ratio data are quantitative, bear no negative numerical values but can have zero values.
5) It is a) TRUE that your weight recorded at your annual physical would not be ratio data because it cannot be zero.
6) It is a) TRUE that temperature measured in degrees Fahrenheit is an example of interval data.
Interval data can be categorized and ranked, and evenly spaced. On the other hand, ratio data can be categorized, ranked, evenly spaced and has a natural zero value.
7) It is b) FALSE that it is better to attempt a census of a large population instead of relying on a sample.
Conducting a census of a sample is more efficient to collect and analyze than a large population.
8) The appropriate level of measurement for rating bonds for Aard Co Inc. as "B+," while bonds of Deva Corp. are rated "AA" is B) Ordinal.
With ordinal ranking, there are ordered ranks without quantitative attributes.
9) Quantitative variables use D) Interval and ratio levels of measurement.
The differences between quantitative variables and qualitative variables are explained with the attached image.
10) The sampling method that FAA would probably use to measure the peak noise from departing jets is C) Judgment sample.
Judgement sampling relies on an expert's non-probabilistic opinions.
11) The proper sampling technique for a population with groups that have a small amounts of variation within them but large variations among the groups is C) cluster.
Cluster sampling relies on a mini-representation of the population, which is divided into clusters for easy sampling, though each cluster is not homogeneous.
12) The procedure that divides the United States into nine regions combines the cluster and stratified sampling methods.
Thus, based on the further divisions of each of the nine clusters, the cluster sampling method also utilizes the stratified method.
