I looked at that sight and can see the tables but what I have is a table that show the heights of students in a class males on top females on bottom with heights out beside them. I have to make a cumulative frequency table from the data in my collumns I have, height,frequency and cumulative frequency four rolls below them. on the males I have 14 different heights and females 11 and Im not understanding how im supposed to get four heights out of all of those and and four frequency and 4 cumulative frequency
Develop four equal height intervals that will include all the data. Within each interval, combine the heights of males and females, starting with the shortest interval on your left. Thereafter, combine that frequency with the male-female frequency in the following intervals to show cumulative frequency. Follow the examples set in the source that Ms. Sue gave you.
I hope this helps a little more. Thanks for asking.
show me a display of a frequency table.
To make a cumulative frequency table, you need a set of data with individual values. Here are the steps to create a cumulative frequency table:
1. Organize your data: Arrange your data in ascending order from lowest to highest. This step ensures that your cumulative frequency table will be accurate.
2. Determine the class intervals: Decide on the range or size of each interval. The class intervals should be mutually exclusive and collectively exhaustive. For example, if you have values ranging from 1 to 50, you might choose a class interval of 10. This means that the first interval would include values 1-10, the second interval would include values 11-20, and so on.
3. Create the table: Create a table with two columns. The left column will contain the class intervals, and the right column will have the cumulative frequency.
4. Calculate the cumulative frequency: Starting from the lowest class interval, count the number of data values falling within or below each interval, and record the cumulative frequency in the right column. Continue this process for each interval until you reach the highest class interval.
5. Optional: Add a cumulative relative frequency column: You may choose to include a third column for cumulative relative frequencies, which represent the proportion of the total data set represented by each cumulative frequency. To calculate the cumulative relative frequency, divide the cumulative frequency for each interval by the total number of data values.
By following these steps, you can create a cumulative frequency table to analyze and interpret your data.
