Why do you need an average?
You need an average because it helps you compare your results.It helps you be more accurate and have more precision.
If the standard deviation of a population is zero what can you say about the members of that population?
Everyone is average, whether that average is the mean, median, or mode.
What is the formula of average income?
average income of a country = total income of the country÷ population of the country
Differentiate accurate from precise in measurement?
Accuracy is when the result is close or equal to the actual value or expected result. Precision is when multiple results are within the same or very close value. With multiple results, you can have accuracy and precision if the results are on target, and all within a very close range. However, if the results have quite a bit of deviation among them, but the average result is on target, then you have accuracy, but low precision. If multiple results are way off target, but are all within a close range of each other, then you have low accuracy and high precision. If the multiple results are all over the place, and the average result is off target, then you have low accuracy and low precision. For example, it helps to imagine a dart board with a few darts. If all the darts are together after being thrown, that is precision. When the thrown dart is close to the bullseye, that is accuracy. IF the darts are all close together and all on the bullseye - that is accurate and precise...if they are all close together, but way off the bullseye, then that is precise but NOT accurate, and so on...
What is the average on IQ test?
The average IQ is 100, with two-thirds of the population having IQs between 85 and 115, and 95% of the population having IQs between 70 and 130.
A sample average can be used to estimate a population average precision if the sample is?
large
How many people have migrated to Australia from Indonesia?
26,302 Estimated resident population in 2006. 31,223 Estimated resident population in 2010. That is an average of 1230.25 increases each year.
Is it true that when increases the average kinetic energy of the particles decrease?
No. It is the opposite. When temperature increases, the average kinetic energy of the particles also increases.
The law of large numbers?
The law of large numbers is a principle of probability and statistics. It states that as a sample size increases, its mean will get closer to the average of the whole population.
Why do you need an average?
You need an average because it helps you compare your results.It helps you be more accurate and have more precision.
Is it true that temperature increases the average kinetic energy increases?
Yes, that is true.
Degree of precision?
average +/- the highest minus the lowest value/2 would be the final answer
How does a substances temperature change when the average kinetic energy of it's particles increases?
As the average kinetic energy of a substance increases, the temperature will increase.
Could the temperature of a material increases the average of its particles also increase?
If the temperature of a material increases, the average kinetic energy of its particles will increase.
When latitude increases does temperature decrease?
The close the latitude is to 0, the hotter it is.
How is the temperature of a substance affected by a change in the average kinetic energy of its molecules?
Directly proportional-- If average KE increases, temperature increases, and vice versa.
How might gentrification affect Americans demographics?
Gentrification increases the average income in city neighborhoods
