A researcher is interested in determining if infant crying and caretaker responses are different in developed and developing nations. She trains her research assistants to watch and record babies behaviors in 3-minute increments, including variations in crying (e.g., whimpering, pain cries, etc.), as well as caregiver responses (e.g., holding, speaking, etc.). She then chooses 50 participants in four different countries to be included in her study. What type of research design is she using?

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A researcher is interested in determining if infant crying and caretaker responses are different in developed and developing nations. She trains her research assistants to watch and record babies’ behaviors in 3-minute increments, including variations in crying (e.g., whimpering, pain cries, etc.), as well as caregiver responses (e.g., holding, speaking, etc.). She then chooses 50 participants in four different countries to be included in her study. What type of research design is she using?

A	Naturalistic observation
B	Case study
C	Survey research
D	Correlation

Explanation:

Detailed explanation-1: -Experimental research allows the identification of causal relationships between entities or events. Successful experimental research depends on well-defined research hypotheses that specify the dependent variables to be observed and the independent variables to be controlled.

Detailed explanation-2: -The defining feature of a cross-sectional study is that it can compare different population groups at a single point in time. Think of it in terms of taking a snapshot. Findings are drawn from whatever fits into the frame.

Detailed explanation-3: -Confirmation bias The intense motivation to collect data in support of a hypothesis can cause researchers to selectively notice and remember information that aligns with their hypothesis. This biased interpretation of data is referred to as confirmation bias.

Detailed explanation-4: -Which of the following is among the questions a reader should ask in assessing the internal validity of a study? Were the methods appropriate for the goal of the study? To what other populations might the result apply?
