While there are several types of estimators, the word “estimator” on its own usually refers to a point estimate. A point estimate is a single value (as opposed to an interval, like a confidence interval). For example, the mean is a point estimate. The two characteristics of point ...
Point estimatesare single values that are used to estimate population parameters (such asmeans, proportions, andvariances). For example, if we wanted to estimate the mean age of all dog owners in the United States, we could use the point estimate provided by our sample mean age. ...

The score went down last month and she want’s to know why. Looks like you’ll have to hunt around to find a reason for the change; or will you? Just because your survey score has gone down, or up, doesn’t mean that there has actually been a change in the overall business NPS....
In this case, by setting the interval parameter, you tell Pyinstrument to take a snapshot every one-tenth of a second or one hundred milliseconds. Then, you estimate the value of pi using a Monte Carlo method with ten million iterations. A frequency of 0.1 seconds is pretty low, so it’...
We assume her income grows 1.5% a year (after inflation) to about $100,000 by the time she is 67 and ready to retire. To maintain her preretirement lifestyle throughout retirement, we estimate that about $45,000 each year (adjusted for inflation), or 45% of her $100,000 pre...
Confidence intervals can be a difficult concept to grasp but they just make intuitive sense when explained in simpler terms. In essence, confidence intervals are as simple as casting a net around information in the form of the point estimate so we capture the true value inside our net. At le...
