Statistics
Statistics deals with collecting, organizing, and interpreting numerical data. An important aspect of statistics is the analysis of population characteristics inferred from sampling.

If you take off the outlier does it make the mean change?
Yes, it will. An outlier is a data point that lies outside the normal range of data. This means that if it is factored in the mean will move in the direction the outlier is, really high if the outlier was high, and really low if the outlier was low.
How many outcomes are possible when rolling 5 number cubes at one time?
There are 65 = 7776 possible outcomes. However, if the number cubes are indistinguishable, then these represent 378 distinct outcomes.
What is the difference between a linear scale and a non linear scale?
Linear is a straight line and non linear could be a curve or anything but a straight line
How can aliasing error be avoided?
Aliasing error can be avoided by using appropriate sampling techniques, such as the Nyquist theorem, which states that a signal should be sampled at least twice its highest frequency to accurately reconstruct it. Implementing anti-aliasing filters before sampling can also help by removing high-frequency components that could cause distortion. Additionally, increasing the sampling rate can reduce the risk of aliasing by capturing more detail in the signal.
What are the different kinds of variables?
The main ones you need to know on a basic level are categoric and continuous. Categoric ones you will display on a bar chart as they are fixed units. Eg plastic or a range of no.s lumped in together
Continuous variables are shown on a line graph as they do not have a differentiating X value (category) into which you can separate them
Hope this helps a bit
The three different kids of science variables are independent, dependent, and controlled.
a variable is something you change and there's a independent variable and a dependent variable
in an experiment there are three variables: responding, controlled, and manipulated. manipulated is the variable that is changed by the guy who does the experiment. responding is the variable that changes due to the manipulated variable. the controlled variable is the variable that is controlled throughout the experiment. anyway im not sure if this is what you wanted to know
Aitutaki is actually an island. It is one of the many Cook Islands, which are located north of Rarotonga. Aitutaki was previously known as Ararau.
What are the advantages and disadvantages of primaries caucuses and conventions?
gives disproportionate importance to states like Iowa, more difficult for less wealthy candidates, divides parties and lessens their importance as they have little role in choice. However they are democratic and provide more choice in a two party system.
What is a coefficient and where does it go?
It's the value of a variable, eg 2 is the coefficient of n in the expression 2n
What percent of the world consist of third world countries?
82% Just do the correct caculatory math skills and the scientific answer is 82.354%
How do you work out a cumulative frequency question?
This will purely depend on the question, if you get a frequency chart, (containing only the frequency and how often this was brought, take, etc depending on the question,) add up the frequency one by one and you will have the cumulative frequency. You then (depending on the question) make a chart or a box-plot and follow the question (i.e what if the correlation shown? this would depended on the trend of the data.)
An applet is a piece of code that can be used for graphical user interaction. An applet generally uses java api's for applets. It could be a window/ a dialog box and some such gui.

What does the term Syncretism mean?
= Syncretism = Syncretism consists of the attempt to reconcile disparate or contradictory beliefs, often while melding practices of various schools of thought. The term may refer to attempts to merge and analogize several originally discretetraditions, especially in the theology and mythology of religion, and thus assert an underlying unity allowing for an inclusive approach to other faiths. Nascent Christianity appears to have incorporated many Jewish and pagan cultural elements, through a process of "Christianization" or "baptizing" them to conform with Christian belief and principles, at least partially, whilst discarding theologically or morally incompatible elements.
How many four digit numbers from the digits 1 2 3 4 5?
If the digits can be repeated, then there are (5 x 5 x 5 x 5) = 625 different four-digit numbers.
If the digits can't be repeated, then there are (5 x 4 x 3 x 2) = 120 different four-digit numbers.
If you consider whole numbers,
the largest 5 digit number with repetition is 99999
the smallest 4 digit number without repetition is -9876
Their difference is 99999 - (-9876) = 99999 + 9876 = 109875.
