Mapping Review, Systematic Map - Map and categorize existing literature from which to commission additional reviews and/or primary research by identifying gaps in the research literature. Meta-analysis - A technique that statistically combines the results of quantitative studies to provide a more precise effect of the results.Summary. Conducting a literature review is an essential first step in research to understand the state of the art and identify gaps and challenges in the field. A systematic literature review is a method that defines a series of steps to methodically organize the review. In this article, we present a guide designed for researchers and researchers. A systematic review collects secondary data and is a synthesis of all available relevant evidence that brings together all existing primary studies for review. A systematic review differs from other types of literature review. in several main ways.This literature review used a systematic literature review methodology Tranfield et al. 2003 to analyze differences in personality traits between various subtypes of entrepreneurs. Our literature review examined entrepreneur subtypes and the extent of differentiation made in previous articles between six personality traits. A PRISMA extension for scoping reviews, PRISMA-ScR, has been created to provide reporting guidance for this specific type of review. This extension is also intended to apply to evidence maps, as these share similarities with scoping reviews and involve a systematic search of a body of literature to identify knowledge gaps.
