How are the pieces of a pie chart related to relative frequency?
The pieces of a pie chart represent the parts of a whole, as does relative frequency. The total of the entire pie chart should be 100% or 360 degrees. The sum of the relative frequencies should also equal 100%.
How do you calculate absolute frequencies?
Absolute frequencies are calculated by first identifying intervals based on your data and then identifying the number of values within your data set that lie within these interval. Relative frequencies divide the absolute frequencues by the number of values in the set. It is a good practice to provide the absolute frequencies, perhaps in a bar chart of relative frequencies as a number above each bar.
What is the definition of pie chart?
As per the dictionary, a circular chart cut by radii into segments illustrating relative magnitudes or frequencies -called also circle graph. See the related link for verification.
How do you do an ogive chart?
You will need endpoints of your range (for example age: 12-14, 15-17. The endpoints are 14 and 17). You will also need the cumulative total of the relative frequencies (add all relative frequencies). -To find the relative frequency = value over total (ex, age 12-14, 51 have diabetes, 90 do not. The total of those having diabetes is 3800. So for the relative frequency of ages 12-14, it is 51/3800=0.01342. Do this for all ranges). -To find the Cumulative Frequency: add all these frequencies (separate for "yes" diabetes and "no" diabetes). Use endpoints of your range for the x-axis (horizontal axis). Then use the cumulative frequencies as your y-axis (vertical axis).
What is the difference between a histogram and a pareto chart?
Both graphs are used to summarize data. Pareto chart is used to establish differences between different groups of data and will assign relative importance to the different groups of data. Histogram is a data distribution graph that will determine if the particular set of data is symmetric or not.

How can you use relative frequencies to create a circle graph of data?
To create a circle graph (or pie chart) using relative frequencies, first calculate the relative frequency of each category by dividing the frequency of each category by the total frequency of all categories. Then, convert these relative frequencies into angles by multiplying each relative frequency by 360 degrees. Finally, draw a circle and partition it into segments based on these angles, ensuring each segment represents the proportion of each category in relation to the whole dataset.
What is tally chart?
a tally chart is achart that contains the frequencies of raw data.
What chart is represented by a circle divided into portions?
A chart represented by a circle divided into portions is called a pie chart. Each portion, or slice, of the pie represents a percentage of the whole, illustrating how different categories contribute to a total. Pie charts are commonly used to visualize relative sizes of parts to a whole, making it easy to compare proportions at a glance.
Which chart compares relative values of different categories to the whole?
The Doughnut chart and pie chart, compares relative values of different categories to the whole
What kind of chart is represented by a circle divided into portions?
A pie chart
What type of graph or chart is to compare relative parts of a whole?
A pier chart is used to compare relative parts of a whole.
Which of the following is a detailed chart that shows the symbols and icons represented in a specific graphic chart?
organizational chart
What part of a graph or chart is used to compare relative parts of a whole?
A pier chart is used to compare relative parts of a whole.
What type of graph or chart is used compare relative parts of a whole?
A pier chart is used to compare relative parts of a whole.
