What is a cumulative frequency table?
You first have to know what cumulative is. . . . . . okay you know that now i font know what to do sorry
How find chi square if only one frequency table is given?
You seem to be referring to the Pearson chi-square test-of-fit statistic. To do this you need not only the observed values in a frequency table (which you have) but the expected (or theoretical) values for that table.In practical situations the expected values are obtained by making some educated guess about what distribution the observed values came from, estimating the parameters of that distribution and then using the estimated distribution to obtain the required expected values to calculate the chi-square.In short, you need more information.
How do you find the mode in a frequency table?
ask your math tutor if you have left school and dont know this then ask your son if you dont have a son then ask your dog if you dont have a dog ask clint eastwood

How tall is a table?
Standard table height is 30 inches.
What are the parts of a frequency distribution table?
In a frequency distribution table, there are usually five parts/columns (12th grade statistics):class, frequency, mid-point, relative frequency, and cumulative frequency.
How many types are there of frequency distribution?
Introduction:Frequency distribution is used to compress and summarize the whole data by grouping the data into classes and records the data points that fall in each class. The frequency distribution is considered as the base for descriptive statistics and they are also used to define the ordinal, nominal and the interval data. Frequency distribution is the comfortable way of grouping and organizing the data.Example of Frequency Distribution:Consider the frequency table for the students in a class where the data has been grouped according to the height of the students. Range of height Total number of student's cumulative frequency3.0 - 4.5 feet 15 154.5 - 5.0 feet 20 355.0 - 6.5 feet 25 506.5 - 7.0 feet 30 80In the case of nominal data the use of the contingency table is required. The frequency distributions are used to present the data graphically.Types of Frequency Distributions:There are three types of frequency distributions. Cumulative frequency distribution,Grouped frequency distribution,Cumulative Grouped frequency distribution.Cumulative frequency distribution (type 1):The cumulative frequency can be found from the frequency distribution by adding the cumulative frequency column. The highest cumulative frequency should be equal to the total number of frequenciesTemperature Frequency Cumulative frequency47 3 2246 3 1945 4 1544 3 1243 3 9Grouped frequency distribution (type 2):The grouped frequency distribution can be formed by grouping the values together into the class intervals. The range can be calculated using the maximum and the minimum values.Data set for temperature45 48 47 43 4442 45 43 46 4645 47 46 47 4543 47 45 47 4644 43 44 46 47The grouped frequency distribution is given byClass interval midpoint frequency45- 47 46 1542 - 44 43 7Cumulative grouped frequency distribution (type 3):In cumulative frequency distribution the cumulative frequency column is added to the grouped frequency distribution so that we can get the cumulative grouped frequency distribution.Class interval midpoint frequency Cumulative frequency45- 47 46 15 2242 - 44 43 7 7
How do you make a cumulative frequency table?
Given a frequency table,the first cumulative frequency is the same as the first frequency;the second cumulative frequency is the sum of the first cumulative frequency and the second [ordinary] frequency;the third cumulative frequency is the sum of the second cumulative frequency and the third [ordinary] frequency;and so on.An alternative definition is that the cumulative frequency for any value is the sum of all the frequencies less than or equal to that value.
What is the fx column in a frequency distribution table?
The fx column in a Frequency Distribution Table is the frequency (f) multiplied by the Class Centre or score (x). If the score is 22. And the freqency for that score is 7. fx = 22*7 = 154 You can use the total of the fx column to find the mean. The total fx divided by the total frequency = Mean.
How do you make a tally table and frequency chart?

What does the cumulative frequency show?
For any given value, a cumulative frequency table of chart shows the number of observations which are less than or equal to that value.
How do you work out a cumulitive frequency?
in a maths question, you have a table. you add up the frequency column, but every time you add something, you write it down, e.g. frequency cumulative frequency 1 1 5 6 3 9 6 15 and so on :)
