Single Variable Analysis

Match each preliminary analysis activity with its correct description.

In psychological research, what is the primary purpose of conducting preliminary analyses before addressing the main research questions?

A psychology researcher has completed data collection for a study investigating the relationship between stress levels and memory performance. Arrange the following steps in the correct chronological order they should follow to conduct a scientifically sound analysis.

A researcher is using a 10-item questionnaire to measure 'academic stress.' Before testing their main research question, they calculate the degree to which all 10 items correlate with one another to ensure the scale is reliable and functioning as a unified tool. This specific component of the preliminary analysis phase is known as assessing ______.

A researcher evaluates their data-cleaning process and decides that calculating reliability coefficients ($\alpha$) for an established scale is redundant because the scale was already validated in previous literature. This evaluation of the preliminary analysis phase is scientifically sound.

In the process of developing a research report, you must construct a standardized protocol for 'Preliminary Analyses' after collecting data from a 12-item 'Social Connectedness' scale and 'Daily Screen Time' logs. Which of the following sequences of actions represents the most appropriate synthesis of procedures to validate your data before addressing your primary research questions?

Before addressing their primary research questions, researchers conduct _____ analyses to evaluate the quality and characteristics of their data.

A psychology researcher administers a 10-item self-esteem scale, a reaction time test, and a demographic survey. To properly conduct preliminary analyses before testing their main hypothesis, they should calculate the internal consistency of the self-esteem scale, check the individual distribution of reaction times, and check for outlier scores.

A researcher is analyzing data from a study on stress and memory. Match each specific analytical action to the corresponding component of preliminary data analysis it represents.

A researcher wants to evaluate and clean their dataset before testing their primary hypothesis that sleep quality predicts exam performance. Order the steps of their analysis workflow from first to last to ensure valid, high-quality conclusions.

Before addressing primary research questions, researchers typically conduct a phase of preliminary analyses. Describe the overall purpose of this phase and list the three specific activities it typically involves.

Based on the standard procedures for data analysis, diagnose what the student did wrong in their workflow and explain the specific preliminary steps they skipped before addressing their primary research question.

A researcher is preparing to test their main hypothesis using a dataset that includes a new 12-item survey for social anxiety. If the researcher wants to confirm that all 12 items reliably operate together before proceeding, which specific preliminary analysis step should they apply?
