Expert writing Tips

Best practice

When using "fraction of times" in scientific writing, ensure you define the sample space or total number of trials to provide context for the fraction.

Common error

Avoid assuming that a high "fraction of times" automatically indicates a causal relationship. Always consider potential confounding variables and statistical power.

Linguistic Context

The phrase "fraction of times" functions as a quantifier, specifying how frequently an event or condition occurs within a given set of trials or observations. It describes a proportional relationship between the occurrences of an event and the total number of opportunities for it to happen, as supported by Ludwig's examples.

Ludwig's WRAP-UP

The phrase "fraction of times" is a versatile quantifier predominantly used within scientific and technical domains to express the frequency of an event's occurrence, as validated by Ludwig AI. Grammatically sound, it conveys precise proportional relationships, making it suitable for objective analysis. While alternatives like "percentage of instances" exist, "fraction of times" maintains a formal tone often required in research and academic writing. To ensure clarity, particularly in statistical contexts, define the sample space. Despite its prevalence, remember that correlation doesn't equate to causation. Ludwig’s analysis suggests that while prevalent in science (98%), its presence in news and formal business contexts is minimal (1% and 0.2% respectively).
