Given below is a back-to-back stem-and-leaf diagram in which common stems are placed at the center of the diagram while the leaves of the two data set are listed at the left and right hand side of the given stems. The following back-to-back stem-and-leaf diagram determines the time in seconds for the two groups of participants to solve a puzzle when exposed to different noise level. The first group of participant solves the puzzle in the classroom wherein the noise level is maintained at 60 decibel. For the other group, a decibel level of 45 was maintained while they solved the same problem.

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
