Which of the following best ensures an accurate mitotic index count in cell analysis?

Choosing to examine a large number of fields of view is crucial for ensuring an accurate mitotic index count in cell analysis. The mitotic index is the ratio of dividing cells to the total number of observed cells, so obtaining a representative sample is essential for accuracy. By analyzing multiple fields of view, one can account for variability in cell distribution and stages of the cell cycle within a tissue or cell culture. This comprehensive approach minimizes the chance of skewed results that could stem from observing only a limited number of areas, which might not reflect the overall population's mitotic activity. Therefore, this method provides a more reliable estimate of the mitotic index.
