Mean‚ median‚ and mode are differing values that furnish information regarding a set of observations. The mean is used when one desires to determine the average value for data ranked in intervals. The median is used to learn the middle of graded information‚ and the mode is used to summarize non-numeric data. The mean is equal to the amount of all the data in a set divided by the number of values in that set. It is typically used with continuous figures. The result will probably not be one of the

1.PERCENT ● DEFINITION OF PERCENT - Percent means parts per 100 The symbol is % Example: 25% means 25 per 100 ● CONVERSION TECHNIQUES - ✔Changing percent to decimal Change a percent to a decimal. Move the decimal point two places to the left. In a percent‚ the decimal point would come at the end of the last number (for 75%‚ envision that it looks like 75.) Examples: 75% converts to .75 40% converts to .40 3.1% converts to .031 ✔Changing decimal or whole number to percent Change a decimal

How does the calculator results compare to the mean and absolute deviation? How do these results compare to your own individual data? Which method is more accurate? The mean was 10 g/mL‚ while the calculator’s results for the line of best fit showed that the density was 9.615736862 g/mL. This is not a large difference‚ but the calculated average is more accurate in comparison to the accepted value of the density of lead‚ or 11.343716 g/mL. The average absolute deviation‚ when done by hand‚ was

Mean and Standard Deviation The mean‚ indicated by μ (a lower case Greek mu)‚ is the statistician ’s jargon for the average value of a signal. It is found just as you would expect: add all of the samples together‚ and divide by N. It looks like this in mathematical form: In words‚ sum the values in the signal‚ xi‚ by letting the index‚ i‚ run from 0 to N-1. Then finish the calculation by dividing the sum by N. This is identical to the equation: μ =(x0 + x1 + x2 + ... + xN-1)/N. If you are not

Fractions are ways to represent parts of a whole. Common fractions are ½ and ¾. These are proper or regular fractions. Some fractions are called mixed numbers. These are represented by a whole number with a fraction (proper fraction). 1 ½ and 2 ¾ are good examples. An improper fraction has a larger number on the top than on the bottom‚ such as 9/8. I will explain how to convert these fractions to decimals. I will show you how to change an improper fraction to a mixed number. Operations (addition
