Multiply the number of, for example, pets, to its frequency. After you get the product, add all of those products up.
E.g.:
Number of pets:Frequency
1:8
2:6
3:3
4:2
5:0
6:1
(1*8) + (2*6) + (3*3) + (4*2) + (5*0) + (6*1)
= 8 + 12 + 9 + 8 + 0 + 6 = 43.
The sum is 43.

What is the plural of frequency?
The plural of frequency is frequencies. As in "radio waves travel on different frequencies".
Frequency and cumulative frequency are two types of what?
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
The first class in a relative frequency table is 50-59 and the corresponding relative frequency is 0.2What does the 0.2 value indicate?
The sum of the relative frequencies must equal 1 (or 100%), because each individual relative frequency is a fraction of the total frequency. The relative frequency of any category is the proportion or percentage of the data values that fall in that category. Relative frequency = relative in category/ total frequency It means a number in that class appeared 20% of the total appearances of all classes
What is the difference between frequency distribution and relative frequency distribution?
Frequency distribution refers to a set of frequencies with a particular set of values into which a statistical population is grouped. Relative frequency refers to data presented in a table that demonstrates the relative frequency of multiple non-overlapping classes.
Is a histogram a graph that represents the cumulative frequencies for the classes in a frequency distribution?
No it is not. The ogive is a graph that represents the cumulative frequencies for the classes in a frequency distribution.
What is the cumulative column frequency distribution table?
Cumulative Frequency is The total of a frequency and all frequencies so far in a frequency distribution. It is the 'running total' of frequencies in the frequency distribution table.
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 sum of relative frequency percents?
The sum of a complete set of relative frequencies will be 100.
Frequency and cumultive frequency are two types of?
Data representation. Cumulative frequency is the sum of all previous frequencies.
How do you figure the percentage in a frequency table?
You find the total of all the frequencies, N. Then the percentage for any frequency is 100*frequency/N.
What is the frequency in a frequency table?
The frequency in a frequency table is the number of occurrences within each class width. The total frequency is the sum of all frequency's within all the classes.
In a population the sum of the relative frequencies of all alleles for a particular trait is?
Gene or allele frequency
What is the sum of products divivded by sum of frequencies?
Assuming the products are created from a dataset which contains each value once or more times by multiplying the each value by its frequency in the dataset, then the result of sum of products (of values by their frequencies) divided by sum of frequencies is the mean average of the all the values in the dataset.
What is a joint frequency?
Entries in the body of a two-way frequency table that show the count (the frequency) for each combination of those two categories. Example: The highlighted numbers in the body of the table are joint frequencies.
How do you find the mean in a frequency distribution table?
A Gaussian distribution has the mean at the highest value. Sum all the values and divide by the number of values. * * * * * A very partial answer and one that does not address the question which was in the context of a frequency distribution table. If the frequencies are for grouped data, replace the range of each group by its midpoint. This, then, comprises the set of values, x, for the random variable. For each x there is an associated frequency, f. Multiply each x by its frequency and add these together. Divide the answer by the sum of the f values. That is the mean.
Why two frequencies are used in dtmf?
The tone frequencies, are selected such that harmonics and intermodulation products will not cause an unreliable signal. No frequency is a multiple of another, the difference between any two frequencies does not equal any of the frequencies, and the sum of any two frequencies does not equal any of the frequencies.
Definition of ogive diagram?
An ogive is a type of graph that is used to represent the cumulative frequencies for the classes in a frequency distribution. This type of graph can also be known as a cumulative frequency graph. The cumulative frequency is the sum of the frequencies accumulated up to the upper boundary of a class in the distribution.
