Point Estimates: A specific number known as the point estimate provides an estimate of the population parameter. The Maximum Likelihood estimator and the Method of Moments are two common techniques used to produce Population Parameter Point, estimators.
Confidence Interval: The confidence interval provides a range of values that most likely contain the population parameter. It even reveals the likelihood that the population parameter may be found in that specific period. The likelihood or similarity is represented by the Confidence Coefficient (or Confidence level), which is indicated by 1-alpha. The significance level is indicated by alpha.
