A study to compare different methods of estimation was conducted. The goal was toprovide an estimate for the number of petal colors existing in the field by using a random sample ofLycoris longituba flowers taken from the field. Three methods of estimation were used to estimate theactual number of the colors in the field. Using the variance analysis, the maximum number of colorswas obtained at 5% risk being in error. The study revealed that the estimation from observed sample(Fisher's method) agrees very well with third order Jackknife method of estimation.
