What would be a better tool for measuring spread and center in statistics?
The answer will depend on what the comparison is to be made with and also on how "better" is being judged. The arithmetic average is the best linear unbiased estimate as well as the maximum likelihood estimate of the centre. The best estimate for the spread depends on whether the data comprise the population or a sample from the population.
How can you use statistics?
Type your answer here... example would be to determine average rate of population growth in order to estimate future tax revenues.
What is a straight a average?
traditionally a straight 'a' average is achieved when a student's final marks for ALL subjects taken are 90% or higher.
About how many people average have the same birthday?
Current world population divided by 365 days in a year. As of 22:36 27/9/13 it is about 7,148,230,000 7,148,230 / 365 = 19,584,200 To work it out accurataly, visit 7billionandme.org, it shows an accurate estimate of the current world population.
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.
Is the point estimate the same as the average?
No. The average of a dataset is the point estimate for the mean of the population.
A sample average can be used to estimate a population average precision if the sample is?
large
What is the average heartbeats per min?
The average persons heart beats 72 times per min
How many times would your heart beat a week?
For typical adults, their heart beats at an average time of 60 beats a minute. A day has 1440 minutes. Since there are 7 days a week, there will be 10080 minutes. 1 hour - 60 minutes 60 minutes x 24 hours = 1440 minutes 1440 minutes x 7 days = 10080 minutes About 60 heartbeats per minute 10080 minutes x 60 heartbeats = 604800 heartbeats Conclusion: An adult's average heartbeats is 604800 heartbeats.
How do you compute the point estimate of a population mean?
To compute the point estimate of a population mean, you take the sample mean. This is done by calculating the average of the data values in the sample. The sample mean is then used as an estimate of the population mean.
What is the average number of heartbeats in a minute des a cat have?
Anywhere between 140-220 is considered normal and healthy
Differentiate estimate and estimator?
It can get a bit confusing! The estimate is the value obtained from a sample. The estimator, as used in statistics, is the method used. There's one more, the estimand, which is the population parameter. If we have an unbiased estimator, then after sampling many times, or with a large sample, we should have an estimate which is close to the estimand. I will give you an example. I have a sample of 5 numbers and I take the average. The estimator is taking the average of the sample. It is the estimator of the mean of the population. The average = 4 (for example), this is my estmate.
What are the average heartbeats in children?
In fetus and new born 140 to 150. Then the number gradually reduces to about 70 to 90 in the adults.

How many heartbeats are there in each hour?
The average heart-rate (at rest) for an adult human is 60-70 beats per minute.
