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
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.
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...
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.
How does a substance 's temperature change when the average kinetic energy of it's particle increases?
As the average kinetic energy of the particles in a substance increases, the temperature of the substance also increases. This is because temperature is a measure of the average kinetic energy of the particles in a substance. So, when the average kinetic energy increases, the temperature increases as well.
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.
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.
What is the difference between the sample of the population and the average of the population?
A sample of a population is a subset of the population. The average of the population is a statistical measure for some variable of the population.
What property of a substance corresponds to the average ke of its particles?
The temperature of a substance corresponds to the average kinetic energy of its particles. As temperature increases, the average kinetic energy of the particles also increases.
How might gentrification affect Americans demographics?
Gentrification increases the average income in city neighborhoods
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.
What will happen to the average speed of an object if the distance increases but the time decreases?
If the distance increases but the time decreases, the average speed of the object would increase. This is because speed is calculated as distance divided by time, so when distance increases and time decreases, the ratio of distance to time increases, resulting in a higher average speed.
