Cross-Sectional Research01:50

Cross-Sectional Research

11.5K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Experimental Designs

11.3K
An experimental design is a systematic process that allows researchers to evaluate the relationship between dependent and independent variables. There are three widely used types of experimental design - pre-experimental design, true experimental design, and quasi-experimental design. In pre-experimental design, the researcher compares the data before and after some interventions or treatments. The true-experimental design has more than one purposefully created group, a commonly measured...

Surveys

14.3K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Group Design

9.3K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Data Collection by Experiments01:13

Data Collection by Experiments

24.5K
Data collection is a systematic method of obtaining, observing, measuring, and analyzing accurate information. An experimental study is a standard method of data collection that involves the manipulation of the samples by applying some form of treatment prior to data collection. It refers to manipulating one variable to determine its changes on another variable. The sample subjected to treatment is known as “experimental units.”
An example of the experimental method is a public...

What is a Mode?01:07

What is a Mode?

20.3K
The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set.
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...

Summary

Mixed-mode survey approaches, combining methods like mail and face-to-face interviews, can lower costs without sacrificing response rates for screening surveys. However, the order of modes may affect follow-up interview participation.

Area of Science:

  • Survey methodology
  • Social sciences research

Background:

  • Growing interest in multi-mode survey approaches due to rising costs and internet adoption.
  • Limited empirical evidence on the cost and error impacts of multimode surveys.

Purpose of the Study:

  • To evaluate if a mixed-mode approach reduces costs compared to face-to-face interviewing for a large screening survey.
  • To assess the impact of mixed-mode strategies on response rates in survey research.

Main Methods:

  • An experiment within the Health and Retirement Study (HRS) comparing different sequences of mail and face-to-face interview modes.
  • A control group receiving only face-to-face interviews for a household screening survey.

Main Results:

  • Mixed-mode survey options demonstrated reduced costs for the screening interview.
  • Response rates for the initial screening interview were not negatively impacted by mixed-mode approaches.
  • The sequence of survey modes may influence response rates for subsequent in-depth interviews.

Conclusions:

  • Mixed-mode survey designs offer a cost-effective alternative to traditional face-to-face screening.
  • Careful consideration of mode sequencing is important for maximizing participation in multi-stage survey research.
