A statistical question is
a question that can be answered by collecting data that vary
. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
What is an example of a non-statistical question?
You don’t need to gather several points of data to answer the question. For example, the question, ‘
What is 2 plus 2?’
is a non-statistical question. This question has only one correct answer that doesn’t change.
What are two types of statistical questions?
We use two types of data to answer statistical questions:
numerical data and categorical data
.
What are statistics examples?
A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then
the average number of points earned by students in that one math class at the end of the term
is an example of a statistic.
What is considered a statistical question?
A statistical question is
one that can be answered by collecting data and where there will be variability in that data
. For example, there will likely be variability in the data collected to answer the question, “How much do the animals at Fancy Farm weigh?” but not to answer, “What color hat is Sara wearing?”.
What are some good statistical questions?
Example: “How many minutes do 6th grade students typically

?” Yes, it is a statistical question. Non-Example: “How much time do you spend watching TV each week?” No, it is a statistical question.
Is a yes or no question statistical?
In general, a
statistical question
is one in which the population is specified, variable answers are anticipated, and the question asks for interesting information. Many times, students will write questions which can be answered with only two choices: yes or no.
How do you know if something is statistical or Nonstatistical?
Statistical Statistical questions require collection of data and the answers have variability (there is more than 1 possible way to answer the question). Non-Statistical Non-Statistical questions
have answers with no variability
(there is only 1 answer).
What is not a statistic?
: not of, relating to, based on, or employing the principles of statistics : not statistical a nonstatistical
analysis Any sample where the sample items are not selected according to the laws of chance
—that is, by probability sampling—is a nonstatistical sample.— Howard Sibelman.
Is how tall is the Eiffel Tower a statistical question?
Is how tall is the Eiffel Tower a statistical question? It stands at a height of 300 meters, that is, 984 feet tall. It is

.
How do you calculate statistics?
Calculate the T-statistic
Divide s by the square root of n
, the number of units in the sample: s ÷ √(n). Take the value you got from subtracting μ from x-bar and divide it by the value you got from dividing s by the square root of n: (x-bar – μ) ÷ (s ÷ √[n]).
How do u do mean in math?
To find the mean,
add up all the values in the set. Then divide the sum by how many values there are
. So if you have five values, add them all together, then divide the result by five. That is the mean.
What is a categorical question in math?
Categorical data is
a collection of information that is divided into groups
. … Categorical data can take on numerical values (such as “1” indicating Yes and “2” indicating No), but those numbers don’t have mathematical meaning. One can neither add them together nor subtract them from each other.
