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?

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.

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 is the population of Japan?
The population of Japan (proper) is about 128 million, which is the figure from the census of 2010. However, a lower estimate of about 126.6 million was promulgated in 2012. This does not mean that the population decreased, but that different figures were used in the computation. The Japanese official monthly estimate for March 2013 was 127,360,000. That is about the average of the other figures.
