The simple method toanalyze the distribution of data set is constructing the frequency distribution.The stages for constructing the frequency distribution are as follows1. Write the values in ascending order. We obtain the ordered data set{X1, X2, ...,XN}where xN is maximum values of observations and x, is minimum2. Group the values into intervals. The number of intervals K is calculated by Sturges formulaK = 1+ log2 N = 1+3.322· log10 Nthe resulting value of K is rounded up to an integerThe length of each interval L is calculated by formulaIx - NXKL =3. Find the number of times a particular x¡ value occurs in the respective interval Ii, i = 1, ... , K.The obtained number n; is named frequency.4. Calculate the relative frequency of a values w;(It is the fraction or proportion of times the valuesoccurs)niW; =

Histogram is used to measure the shape of the data set. It explains whether the data is symmetrical…

Choose the best statement to summarize the association shown between hat size and IQ in the scatterplot below. Hat Size O The scatterplot does not show a trend that would indicate an association between hat size and IQ scores. O As hat size increases, IQ scores tend to decrease.
