Holes is a young adult novel written by Louis Sachar and published in 1998. It tells the story of Stanley Yelnats, a teenage boy who is falsely accused of stealing and sentenced to serve time at Camp Green Lake, a juvenile detention center in Texas. At the camp, Stanley and the other boys are required to dig a hole five feet wide and five feet deep every day as punishment and rehabilitation.

As Stanley begins his sentence, he quickly realizes that Camp Green Lake is unlike any other detention center he has ever heard of. The camp is located in a dry, desolate area with no lake, no trees, and no shade. The boys are given only one pair of shoes, one pair of socks, and one set of clothes, and they are not allowed to speak to each other or ask questions. The warden, Mr. Sir, and the counselor, Mr. Pendanski, are both cruel and abusive, and the boys are constantly hungry and thirsty.

Despite these difficult conditions, Stanley is determined to survive his sentence and return home to his family. As he digs his daily hole, he begins to uncover clues about the history of Camp Green Lake and the reason why the boys are required to dig. He learns that the camp was once a thriving community with a beautiful lake, but that the lake dried up and the town died when a group of criminals stole a valuable object from a wealthy man named Sam the Onion Man.

As Stanley and the other boys continue to dig, they uncover more and more clues about the past, including old coins, bones, and even a stolen bicycle. They also discover that the warden and Mr. Sir are searching for something specific, and that they will stop at nothing to find it.

As Stanley and his fellow prisoners work to solve the mystery of Camp Green Lake, they also learn about friendship, perseverance, and the importance of standing up for what is right. They come to understand that, despite the hardships they face, they have the strength and determination to overcome any challenge.

In the end, Stanley and his friends are able to solve the mystery and bring the perpetrators of the crime to justice. They also discover that the warden has been using the boys to dig for the valuable object, and they use this information to blackmail her into releasing them from the camp.

Holes is a beautifully written, poignant, and thought-provoking novel that deals with themes of justice, friendship, and the human spirit. It is a heartwarming and uplifting story that will leave readers feeling inspired and hopeful.

An example of measurement means the use of a ruler to determine the length of a piece of paper. You could order these from biggest to smallest; the difference between the biggest and the middle might be much larger than the difference between the middle and the smallest. Nominal scales are used for labeling variables, without any Examples of Nominal Scales Note: a sub-type of nominal scale with only two categories e. What is quantitative numerical data? In nominal scales, the numbers assigned to each variable or observation are only used to classify the variable or observation. In contrast, the questions for inferential analysis are framed to collect data on the dependent and independent variables of the study.

Scales of Measurement In Statistics, the variables or numbers are defined and categorised using different scales of measurements. As many have already expressed, yours is perhaps one of the simplest and straightforward explanations for an otherwise complex topic. What are the four types of measurement of a variable? In addition, it involves the ranking of variables. Ordinal scales are used to provide information about the specific order of the data points, mostly seen in the use of satisfaction surveys. Ordinal or Ranking Scales 3. Nominal Scale is assigned to items that is divided into categories without having any order or structure, for instance Colors do not have any assigned order, We can have 5 colors like Red, Blue, Orange, Green and Yellow and could number them 1 to 5 or 5 - 1 or number them in a mix, here the numbers are assigned to color just for the purpose of identification, and ordering them Ascending or Descending doesnt mean that Colors have an Order.
