From the bar graph, we see that the students using online homework had a lower percent for As, but had a higher percent who passed with a C or better. The sum of all the relative frequencies of a distribution will always add up to 1. Subsequently, there was a decreasing trend. How is the bar graph misleading? C The trend is depicted in the wrong direction. Did not come with an access code as advertised.
The content contained on these pages was developed for Mth - Statistics I at Elgin Community College, to coincide with the textbook Statistics: Chapter 1: Data Collection printable. Chapter 2: Organizing and Summarizing Data printable.
Chapter 3: Numerically Summarizing Data printable. Chapter 4: Describing the Relation between Two Variables printable. Chapter 5: Probability printable. Chapter 6: Discrete Probability Distributions printable. Chapter 7: The Normal Probability Distribution printable.
Chapter 8: Sampling Distributions printable. Chapter 9: Construct the requested frequency distribution. Construct a frequency 40 distribution and a relative frequency distribution using five classes. Round relative frequency values to three decimal places. Using a class width of 10, give the upper and lower limits for five classes, starting with a lower limit of 95 for the first class.
Construct a frequency distribution for the data Construct the specified histogram.
Create a frequency histogram for the data using a class width of 2. Construct a relative-frequency histogram using a 10 class width of 2. Construct a frequency histogram for the data using a class width of 10 and using 95 as the lower limit of the first class. B The bars in a bar chart may be of various widths while the bars of a histogram are all the same width.
C There is no difference between these two graphical displays. D The bars on a bar chart do not touch while the bars of a histogram do touch. Determine the original set of data. Major League Handbook Construct a stem-and-leaf plot for this data.
Construct a dot plot for the data. Construct a frequency distribution for the data using five classes. Describe the shape of the distribution. A The first is symmetric, but the second is not symmetric.
B Both are symmetric. C The second is symmetric, but the first is not symmetric. D Neither is symmetric.
Construct a frequency polygon using six classes and a class width of 3. Determine whether the statement is true or false. Construct a frequency distribution, a relative frequency distribution, a cumulative frequency distribution, and a relative cumulative frequency distribution using six classes.
Construct the requested ogive. Construct a frequency ogive using five classes. Construct a frequency ogive using six classes.
Construct a relative frequency ogive using six classes. Use a time series plot to display the data.
Explain what is misleading about the graphic. A The length of a side has doubled, but the area has been multiplied by 8. B The graphic is not misleading. C The length of a side has doubled, but the area has been multiplied by 4. D The length of a side has doubled, but the area has been unchanged.
C The trend is depicted in the wrong direction. D The horizontal label is incomplete. C The horizontal scale does not begin at zero. D The graphic only includes information for one year. The number of accidents dropped in after a new speed limit was imposed. How is the bar graph misleading?
How would you redesign the graph to be less misleading?
This year it delivered parcels. How many times larger should the graphic for this year be than the graphic for last year? Relative Frequency Histogram: The leaves will be drawn in the appropriate stems based on the data values. However, beginning in Year 9, there is sign of a decreasing trend.
Subsequently, there was a decreasing trend.
