An outlier causes the mean to have a higher or lower value biased in favor of the direction of the outlier. Outliers don't fit the general trend of the data and are sometimes left out of the calculation of the mean to more accurately represent the value.Know More
An outlier ranges far from the mid-point of the data. It can be either much higher or much lower than the mid-point. Outliers that are much higher than the mid-point of the data inflate the mean, while outliers that are much lower reduce the mean. The inclusion of an outlier in the calculation of the mean depends upon the reasonable expectation of finding an outlier in the data.
The mean is one type of average. It is found by adding a group of numbers and dividing the total by the amount of numbers present in the data set. Median and mode are two other types of averages. The median is found by listing the numbers in numerical order before identifying the middle number in the group. The mode is identified by locating the number that is found most often in the data set. Outliers have much less effect on the median and the mode of a data set.Learn more about Algebra
There are two components to the slope of a line: its direction and its magnitude. Find the slope of a line by observing whether, from left to right, the line rises or falls and whether the line is vertical or horizontal. Then, take the coordinates of any two points on the line and divide the difference in the points' y-axis values by the difference in their x-axis values.Full Answer >
A geometric ray has one endpoint and extends from the endpoint to infinity in one direction on a line. Rays are written with a right-facing arrow over two capital letters. The first letter represents the endpoint, and the second letter represents another point on the ray.Full Answer >
Similar is a term used in math when discussing geometric figures or shapes, and it means that both figures' corresponding sides are proportional, but the figures themselves are two different sizes. So one is basically a larger version of the other.Full Answer >
Calculating the root-mean-square speed of a gas requires measurements of the gas's temperature and mass. The formula also requires finding the square root, which can be calculated on a graphing calculator and some simple calculators.Full Answer >
