<p>The primary advantage of randomization is that it improves the chances that the control and treatment groups have similar characteristics, which helps to eliminate biased estimates and allows researchers to focus on the potential causal impact of the treatment on the outcome.</p> Signup and view all the answers

<p>Cross-sectional data contains information on individual entities at a given point in time, while time-series data contains information on a single entity at different points in time. Cross-sectional data is used to study multiple entities at a single point in time, while time-series data is used to study a single entity over time.</p> Signup and view all the answers

<p>Econometrics is a set of statistical techniques used to establish and estimate causal relationships in observational studies, where randomization is not possible. It helps researchers to control for outside factors and isolate the effect of the variable of interest.</p> Signup and view all the answers

<p>A potential pitfall of experimental studies is response bias, which occurs when the treatment or control group responds differently to the experiment. This can be addressed through careful experimental design, randomization, and accounting for outside factors.</p> Signup and view all the answers

<p>Panel data combines features of cross-sectional and time-series data, containing information on individual entities at different points in time. Longitudinal data, on the other hand, follows the same entity over time. Panel data is used to study individual entities over time, while longitudinal data is used to study a single entity's changes over time.</p> Signup and view all the answers

<p>The primary function of the control group is to serve as a comparison group to the treatment group, allowing researchers to isolate the effects of the treatment and focus on possible causation between the treatment and outcome.</p> Signup and view all the answers

<p>Randomization improves the chances of obtaining unbiased estimates by ensuring that the control and treatment groups have similar characteristics, thereby reducing the impact of outside factors. Biased estimates conflate the true causal impact with the impact of outside factors, leading to inaccurate conclusions.</p> Signup and view all the answers

<p>Experimental studies involve manipulating an independent variable to observe its effect on a dependent variable, whereas observational studies rely on existing data. Econometrics address the limitations of observational studies by using statistical techniques to establish and estimate causal relationships in the absence of randomization.</p> Signup and view all the answers

<p>The primary advantage of using panel data is that it combines the features of cross-sectional and time-series data, allowing researchers to analyze individual entities over time and observe changes in their characteristics. Panel data differs from cross-sectional data in that it provides information on individual entities at multiple points in time, and from time-series data in that it provides information on multiple entities over time.</p> Signup and view all the answers

<p>Some of the pitfalls of experimental studies include ethical issues, technical problems, response bias, limited duration, and generalization of results. These can be addressed through careful design and implementation, such as using placebo controls, ensuring randomization, and selecting appropriate sample sizes and durations.</p> Signup and view all the answers
