You are watching: Which of the following is a common distortion that occurs in graphs?
Refer to the accompanying data collection and also use the 25 house voltage measurements to construct a frequency circulation through 5 classes. Begin through a reduced class limit of 122.0 volts, and usage a course width of 0.2 volt.
Does the result show up to have actually a normal distribution? Why or why not?
Yes, because the frequencies start low, reach a maximum, then come to be low aobtain, and are approximately symmetric around the maximum frequency.
Does the frequency distribution show up to have a normal distribution utilizing a strict interpretation of the relevant criteria?
Construct the cumulative frequency distribution for the offered information.
What is the class width?
What are the class midpoints?
What are the class boundaries?
The table below shows the frequency distribution of the rainloss on 52 consecutive Wednesdays in a specific city. Use the frequency circulation to construct a histogram.
Do the information show up to have a distribution that is approximately normal?
No, it is not symmetric.
The frequency circulation below shows arrival delays for airplane flights.
Use the frequency circulation to construct a histogram. Which component of the histogram depicts flights that arrived beforehand, and also which component depicts flights that arrived late?
The two leftmost bars depict flights that arrived early, and also the other bars to the appropriate depict flights that arrived late.
The histogram to the ideal represents the weights (in pounds) of members of a certain high-college math team.
How many type of team members are consisted of in the histogram?
The frequency distribution listed below represents frequencies of actual low temperatures taped in the time of the course of a 31-day month.
Use the frequency circulation to construct a histogram.
Do the information show up to have a circulation that is approximately normal?
Yes, the distribution does show up to be normal.
The given information represents a frequency distribution of the depth of current earthquakes. Use the frequency distribution to construct a frequency polygon.
Applying a strict interpretation of the demands for a normal distribution, perform the depths show up to be normally distributed? Why or why not?
The frequency polygon does not show up to approximate a normal distribution bereason the frequencies execute not increase to a maximum and also then decrease, and also the graph is not symmetric.
The graph to the ideal supplies cylinders to represent barrels of oil consumed by 2 nations.
Does the graph distort the data? Why or why not? If the graph distorts the data, construct a graph that depicts the data fairly.
