An interpreting test score is a numerical value that represents an individual's level of proficiency. The score is typically based on a standardized test that assesses the individual's ability to accurately convey meaning. The specific scoring system will vary depending on the test, but generally, higher scores indicate greater proficiency in interpreting. Interpreting test scores can be used to assess an individual's language skills for employment, educational, or certification purposes.

Percentile
A percentile is a way of ranking data points in a distribution. Percentiles are often used in standardized testing to compare an individual's performance to a larger group of test-takers. The percentile rank is calculated by dividing the number of scores that are below a given score by the total number of scores, then multiplying by 100. For example, if there are 100 test-takers and your score is higher than 80 of them, your percentile rank would be 80/100 x 100, or 80th percentile. Percentiles can be useful for understanding how an individual's performance compares to others in a particular group or population.
Percentage
Percentage is a way of expressing a number as a fraction of 100. It is often used to represent proportions or rates. For example, if 25 out of 100 students in a class are absent, the percentage of absent students would be 25%. To calculate a percentage, divide the part by the whole and multiply by 100. For example, if you sold 50 out of 100 items, the percentage of items sold would be (50/100) x 100, or 50%. Percentages can be used to compare numbers of different sizes and to understand the relative size of different quantities.
Ordering and ranking
Ordering involves arranging items in either ascending or descending order based on a particular attribute, while ranking involves assigning a numerical rank to each item in a set based on a particular attribute. Both ordering and ranking are useful for organizing data and identifying trends or patterns in the data.
Frequency distribution is a way of organizing data into groups, or bins, based on the values of a particular attribute. Each bin represents a range of values, and the frequency of occurrence of each value within the bin is recorded. The frequency distribution can be displayed in a table or a graph, such as a histogram, which shows the frequency of each bin on the y-axis and the range of values on the x-axis. Frequency distributions are useful for understanding the distribution of data and identifying patterns or trends in the data.
A measure of central tendency is a way of summarizing a set of data by identifying a single value that represents the "center" or "typical" value of the data. The most common measures of central tendency are the mean, median, and mode.
The mean is a measure of central tendency that is calculated by adding up all the values in a data set and dividing the sum by the total number of values in the set. The mean is often referred to as the "average" value of the data set.

The median is a measure of central tendency that is calculated by finding the middle value in a data set when the values are ordered from smallest to largest.

The mode is a measure of central tendency that is calculated by finding the value that occurs most frequently in a data set.
Pictorial form refers to the visual representation of data using graphs, charts, diagrams, or other types of images. Pictorial forms are useful for presenting complex data in a clear and easy-to-understand way, and can help to reveal patterns and relationships that might not be apparent from looking at raw data alone. Common types of pictorial forms include bar graphs, line graphs, pie charts, scatterplots, and histograms. Choosing the right type of pictorial form depends on the type of data being presented and the message that the data is intended to convey.

A graph is a visual representation of data. A polygon is a closed shape formed by connecting points on a graph with straight lines. A histogram is a type of graph used to represent the distribution of continuous data.

Grading is the process of evaluating a student's performance on a particular assignment, exam, or course. The grade is usually represented as a letter.
Reporting results involves communicating the student's grades or scores to parents, teachers, or other stakeholders.
Grading need
Grading is necessary to evaluate a student's level of understanding and progress in a course. It helps to identify areas of strength and weaknesses, and provides feedback to students and teachers about their performance. Grading also serves as a way to motivate students to work harder and to set goals for themselves.
