Question
(Frequency Distribution) Shown below is a STATDISK histogram representing the durations (in hours) of flights of NASA space shuttles. Use the displayed histogram to construct a table representing the frequency distribution, and identify the value of the class width. (Histogram) When trying to better understand the data, what is the advantage of examining the histogram instead of the frequency distribution? (Normal Distribution) When it refers to a normal distribution, does the term "normal" have the same meaning as in ordinary language? What criterion can be used to determine whether the data depicted in a histogram have a distribution that is approximately a normal distribution? Is this criterion totally objective, or does it involve subjective judgment?Explanation / Answer
From given histogram the fregnancy table is,
Class Width = 100
Advantage of examing the histogram instead of frequency distribution is,from histogram we get idea about the shape of the distribution.
When we refer shape of the histogram is normal distribution the term normal has same meaning as in ordanary language. When the shape of the histogram is bell shaped then it is approximately a normal distribution. Yes this criteria is totally objective it does not involve subjective judgement.
