Did you know that one way to determine if a set of data follows a normal distribution is by visually inspecting its frequency distribution? A normal distribution is characterized by a symmetric bell-shaped curve, with the mean and median being equal and the majority of the values clustering around the mean.
To determine if the FICO scores listed above come from a population with a normal distribution, one approach would be to construct a histogram or a frequency distribution table. By plotting the scores to see the shape of the distribution, we can visually assess if it resembles a normal curve or not.
Another method would be to calculate measures of central tendency and dispersion like the mean and standard deviation. If the mean and median are approximately equal and the standard deviation is not too large, it suggests a normal distribution.
Before drawing any conclusions, it is essential to thoroughly analyze the data using statistical techniques or tests designed specifically for assessing the normality assumption.
