Exam 12: Using Basic Descriptive Analysis Performing Population Estimates and Testing Hypotheses

What is parameter estimation? What three values does it use?

The ________ specifies the difference between the endpoints in a set of values arranged in order.

When statistical procedures are used by marketing researchers to generalize the results of a sample to the target population that it represents,the process is referred to as:

Beyond organization,there are guidelines that will ensure that the data presentation tables strongly imply that they are credible and should be taken very seriously.Which of the following is NOT one of those guidelines?

All measures of variability are concerned with depicting the"typical"difference between the values in a set of values.

The problem confronting the marketing researcher when faced with a dataset is ________,which is defined as the process of describing a dataset by computing a small number of statistics that characterize various aspects of the dataset.

There are several measures of variability with each measure providing its own unique version of information that helps to describe the diversity of responses.Which of the following is NOT one of those measures of variability?

Commonly used ________ reveals central tendency(typical response)and variability(similarity of responses).

There are guidelines for presentation of confidence levels.The General Case Approach is not universally the industry standard but is popular with marketing researchers and used with almost all opinion polling.

The ________ is a descriptive analysis measure defined as that value in a string of numbers that occurs most often.

The crux of statistical hypothesis testing is the sampling distribution concept.

Measures of variability reveal the typical similarities between the values in a set of values.

The ________ says that our sample is one of many theoretical samples that comprise a bell-shaped curve with the hypothesized value as the mean.

What is the concept of statistical inference? Discuss the key factor in inference and why it is important.

A ________ is used to approximate the population value(parameter)through the use of confidence intervals.

With a set of numbers,the mode is that number appearing least often.

Values that are computed from a complete census,which are considered to be precise and valid measures of the population,are referred to as:

A researcher may be investigating credit card usage and may want to see if high-income earners differ from moderate-income earners in how often they use American Express.What type of analysis might the researcher choose to compare expenditures by high-income earners versus moderate-income earners?

Population estimation is the process of using sample information to compute an interval that describes the range of a population such as the parameter mean(?)or the parameter percentage(?).

Values that are computed from information provided by a sample are referred to as the sample's:
