Comparing Observations in Histograms

The video tutorial explains how to compare the total number of observations between two histograms, A and B. It involves counting the observations in each histogram, summing them up, and then calculating the difference. Histogram A has a total of 42 observations, while Histogram B has 36, resulting in Histogram A having five more observations than Histogram B.

What is the first step in determining how many more observations histogram A has compared to histogram B?

• Directly compare the total observations of both histograms.

• Estimate the observations based on the histogram's appearance.

• Find the number of observations in each value range for histogram A.

• Count the observations in histogram B first.

After counting the observations in each range for histogram A, what is the next step?

• Compare the observations with histogram B.

• Add up all the observations to get the total for histogram A.

• Count the observations in histogram B.

• Subtract the observations of histogram B from A.
