Arithmetic mean
is the sum of all the observations divided by the total number of observations. A population average is called population mean (μ).
What is the sum all the observations and divided by the total number of observations?
Arithmetic mean
is the sum of all observations divided by a number of observations.
What is the total number of observations?
The number of observations
provides information on the total number of values that are contained in the Dataset
. This property is intended to provide an indication of the size of a Dataset.
What is the ratio of the sum of observations and the total number of observations is called 1?
Answer:
Mean
is the ratio of the sum of all given observations to the total number of observations.

| Data Value Frequency Relative Frequency | 1 4 0.2 | 2 2 0.1 | 3 3 0.15 | 4 3 0.15 |
|---|
Is the total of the sum of all values in a collection of numbers divided by the number of items in a collection?
MEAN
-the sum of a set of numbers divided by the number of items in the set, also referred to as the average. MEDIAN- with a list of numbers that are arranged in numerical order, the median is the middle number. If there are two middle numbers, the median is the average of the two middle numbers.
Is calculated by dividing sum of all observations by the total number of observations?
Answer: On dividing the sum of observation by total number of observation, we obtain
the arithmetic mean
.
When the sum of a set of observations divided by no of observation is?
Sum of all observations divided by total number of observations is called
arithmetic mean
.
What are the two angles called whose sum is 180?
Supplementary angles
are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees.
What is the value of variable which occurs most frequently?
The
mode
is the value that appears most frequently in a data set.
Is found by dividing the sum of the absolute deviations by the number of observations?
Standard deviation is the frequently used measure of dispersion: it uses squared deviations, and has desirable properties, but is not robust.
Average absolute deviation
, is the sum of absolute values of the deviations divided by the number of observations.
Is the sum of the values of given quantities divided by the total number of quantities?
An arithmetic mean
is calculated by adding several quantities together and dividing the sum by the number of quantities.
What is the collection of information collected for a purpose is called?
The collection of information, collected for a purpose is called
data
. Data can also be described as a collection of facts and figures. … Hence the correct option is D i.e. Data.
What is the sum of all the numbers in a set divided by the total frequency?
Most people are familiar with the word “
average
” and many know that to find the average, we add up all the numbers and divide by the total. Another word for the average is the mean. Step 1: Add up all the numbers. The result is called the sum.
Is the sum of all given values divided by the total number of values?
The mean
of a data set is the sum of the values divided by the number of values. The median of a data set is the middle value when the values are written in numerical order.
What refers to the sum of the numbers divided by n?
In mathematics and statistics,
the arithmetic mean
( /ˌærɪθˈmɛtɪk ˈmiːn/, stress on first and third syllables of “arithmetic”), or simply the mean or the average (when the context is clear), is the sum of a collection of numbers divided by the count of numbers in the collection.
Is the sum of the values divided by the total number of values the symbol represents the sample mean?
Taking the
mean
The mean
of a variable is the sum of its values, divided by the number of values.
How do you solve for K?
Since k is constant (the same for every point), we can find k when
given any point by dividing the y-coordinate by the x-coordinate
. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
What is being calculated when the sum of a set of numbers is divided by the actual number of figures added in the set?
The arithmetic mean
is the simplest and most widely used measure of a mean, or average. It simply involves taking the sum of a group of numbers, then dividing that sum by the count of the numbers used in the series. For example, take the numbers 34, 44, 56, and 78.
What is computed by dividing the sum of the squared deviations from the mean by the number of observations in the data set?
The variance
is the average of the sum of squares (i.e., the sum of squares divided by the number of observations). The standard deviation is the square root of the variance.
What does combined mean in math?
A combined mean is
a mean of two or more separate groups
, and is found by : Calculating the mean of each group, Combining the results.
When sum of two adjacent angle is 180 then the angles are called angle supplementary complementary linear pair vertically opposite?
Answer: If sum of two angles is 180, then they are called supplementary angles. If sum of two angles is 90, then they are called complementary angles. These are supplementary angles.
When the sum of the measures of two adjacent angles are 180 degrees and angles are called angles?
If the sum of the measure of two angles is 1800 then the angles are said to be
supplementary angles
, whereas if the sum of measures of two angles is 900 then the angles are called complementary angles.
When the sum of the measures of two angles are 180 angles are adjacent angles B complementary angles C vertically opposite angles supplementary angles?
When the sum of the measures of two angles is 180°, the angles are called
supplementary angles
. Each of them is called supplement of the other. Two angles are called adjacent angles, if they have a common vertex and a common arm but no common interior points.
What is the value of the variable and how often the value occurs called?
The mode of a distribution with a
discrete random variable
is the value of the term that occurs the most often.
How can median be calculated where n is the number of observations in an ordered list and n is odd?
If the number of observations is odd, the number in the middle of the list is the median. This can be found by
taking the value of the (n+1)/2 -th term
, where n is the number of observations. Else, if the number of observations is even, then the median is the simple average of the middle two numbers.
What is collected with a definite purpose is called data?
Facts or numerical figures, collected with a definite purpose, are called
data
. The data obtained in original form is referred to as raw data or ungrouped data. The data condensed into groups or classes is known as grouped data.
What is a collection of facts called?
A collection of facts, if large enough, may be called
an archive
.
What is the number of times a particular observation occurs in a given data called?
The number of times a particular observation occurs in a given data is called
its Frequency
.
Which of the two types of data are collected for a definite purpose?
Only
primary data
is the type of data which is collected for a definite purpose as it is collected by the investigator himself to fulfil his purpose of collecting data.
