Assume that x denotes ay real number.729x63x. Each bar typically covers a range of numeric values called a bin or class; a bar's height indicates the frequency of data points with a value within the corresponding bin. A B Which statistic has the lowest variability among these three? Thus, any sample size will produce a normal distribution for EMBED Equation.DSMT36 . B. Mhm for to the highest frequency is definitely the one that falls on four. So it's not surprising to see random error.  (b) Correlation will increase, slope will stay the same. Stop procrastinating with our smart planner features. A histogram is a graphical display of data using bars of different heights.
