“While statistic are not difficult to understand, they are moreover easier to misunderstand,” Ramos said. “Fortunately, concepts successful statistic are grounded successful intuition and rationality. So, a basal but thoughtful preamble to these concepts tin thief group understand their ain reasoning better.”
At the 2025 Joint Statistical Meetings successful Nashville, Tennessee, a market-research and study institution solicited questions from attendees to see successful a nationwide study fixed to a typical sample of the U.S. population. Ramos and his co-author, Samuel Anyaso-Samuel, postdoctoral chap astatine the National Institutes of Health’s National Cancer Institute, submitted 2 questions that were utilized successful this survey: “How overmuch do you understand astir statistic and p-values?” and “How often would you guidelines decisions connected reported statistic if you understood it better?” Ramos and Anyaso-Samuel analyzed the responses to these questions for this study.
Of the 1,000 group surveyed, one-quarter reported that they had nary knowing of statistics, while 37% reported constricted familiarity. Slightly much than one-quarter said they had learned immoderate statistic successful school.
This does not mean that group do not judge statistic matter, Ramos said. Nine retired of 10 participants said they would usage statistic much if they possessed much understanding.
“Understanding and evaluating the value of grounds should beryllium wrong scope of immoderate willing citizen,” Ramos said. “Statistical literacy is captious erstwhile investigation is invoked successful news reports, societal media aliases argumentation debates that impact people’s lives.”
The study specifically asked whether group understood p-values. In research, a p-value is simply a instrumentality for knowing a study's results. In simplified terms, the smaller the p-value, the greater the statistical evidence, according to Ramos.
"Statistics does not supply certainty," Ramos said. "Rather, it useful pinch the uncertainty coming successful quality and nine to supply a reasonable attack for making decisions. The amended group understand that concept, the much they tin study erstwhile to spot aliases mistrust the statistical grounds they read. Taking the clip and effort to study astir statistic tin thief a personification go a much informed user of science.”
For group who are willing successful statistics, Ramos said location are galore fantabulous free resources available. He noted that Penn State provides the people materials for STAT 200: Elementary Statistics online arsenic a free acquisition resource, moreover to group who are not enrolled successful the class.
