Measurement multiple choice questions

Science learning can seem like learning an alien language. Learning science includes learning and using many new languages - scientific practice terms, content-specific vocabulary and the words associated with new systems - like the metric system of measurement!

In this lesson, students are introduced to the metric system and practice using the metric system to measure many different quantities. Because the metric system is the language of measurement for scientific practice world wide almost!

The understanding that standard units are used to measure and describe physical quantities such as weight, time, temperature, and volume CCC - Scale, proportion, and quantity is a crosscutting concept deeply ingrained in this lesson. Additionally, math standards apply too; students work to understand relative sizes of measurement units within one system of units 4.

An understanding of the metric system allows students to participate in effective collection of data to serve as the basis for evidence to answer scientific questions or test design solutions under a range of conditions SP3. This lesson is the introductory lesson to what amounts to year-long and life-long practice of the metric system. Just as in learning a language, best practice is immersion. While the following related lessons help students learn the unique units and measurement practices for different physical quantities, teaching these lessons in context provides more leverage for student learning.

Rather than embarking on a stand-alone unit for the metric system, students learn and retain the information when they prac tice the skills within the context of meaningful investigation. Measurement: Distance. Measurement: Density. To help students explore the metric system, they participate in a series of activities designed to introduce and build knowledge:.

How does basing a measurement system based the on number 10 make using the system more efficient? Have students view slide 5 of the Metric System Presentation to illustrate the power of 10 and preview metric unit prefixes. Slide 6 shows a map of how few countries don't use the metric system, which visually illustrates to students about the importance of sharing a common language for measurement.

Measurement: Metric

To excite students, have them read this brief excerpt from the Metric Conversion Act and remind them that if they don't use the metric system, they are actually breaking the law! For a fun application for using the metric system, read this section's reflection: Metric Ball Using the Metric System for Fun.

This stage of the lesson presents a great place for a quick formative assessment. A quick review of student work Measuring in Metric Student Work using the Metric System Student Handout Notes as a class is a great way to elicit student explanations and check for understanding:. The novel situation in this case is further understanding of how to convert between metric units. For many students, retention of basic metric units that are commonly used meters, centimeters, millimeters, grams, liters, milliliters, etc.

However, for students with advanced understanding, practice with converting units is developmentally appropriate: Metric System Extensions. As noted in the introduction to this unit, this lesson is a first exposure lesson to the metric system.

Appropriate evaluation after implementation of this lesson would include a basic "remembering" assessment such as Measurement Quiz - Multiple Choice or Measurement Quiz. After students learn the unique units and measurement practices for different physical quantities within the context of meaningful investigation, a more comprehensive evaluation would be appropriate.

Nominal, Ordinal, Interval and Ratio are defined as the four fundamental levels of measurement scales that are used to capture data in the form of surveys and questionnaires, each being a multiple choice question.

Each scale is an incremental level of measurement, meaning, each scale fulfills the function of the previous scale and all survey question scales such as LikertSemantic DifferentialDichotomous etc, are the derivation of this these 4 fundamental levels of variable measurement.

Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options. This scale is the simplest of the four variable measurement scales. Calculations done on these variables will be futile as there is no numerical value of the options. There are cases where this scale is used for the purpose of classification — the numbers associated with variables of this scale are only tags for categorization or division.

Calculations done on these numbers will be futile as they have no quantitative significance. Nominal scale is often used in research surveys and questionnaires where only variable labels hold significance. There are two primary ways in which nominal scale data can be collected:. In both the cases, the analysis of gathered data will happen using percentages or mode,i.

It is possible for a single question to have more than one modes as it is possible for two common favorites can exist in a target population. Ordinal Scale is defined as a variable measurement scale used to simply depict the order of variables and not the difference between each of the variables.

These scales are generally used to depict non-mathematical ideas such as frequency, satisfaction, happiness, a degree of pain etc. Descriptional qualities indicate tagging properties similar to the nominal scale, in addition to which, ordinal scale also has a relative position of variables. Status at workplace, tournament team rankings, order of product quality, and order of agreement or satisfaction are some of the most common examples of Ordinal Scale.

These scales are generally used in market research to gather and evaluate relative feedback about product satisfaction, changing perceptions with product upgrades etc. For example, a semantic differential scale question such as:. Ordinal scale data can be presented in tabular or graphical formats for a researcher to conduct convenient analysis of collected data.

These methods are generally implemented to compare two or more ordinal groups. In the Mann-Whitney U test, researchers can conclude which variable of one group is bigger or smaller than another variable of a randomly selected group. While in the Kruskal—Wallis H test, researchers can analyze whether two or more ordinal groups have the same median or not.

This scale not only assigns values to the variables but also measures the rank or order of the variables, such as:. Learn about: Nominal vs. Ordinal Scale. Interval Scale is defined as a numerical scale where the order of the variables is known as well as the difference between these variables. Variables which have familiar, constant and computable differences are classified using the Interval scale.

These scales are effective as they open doors for the statistical analysis of provided data. Mean, median or mode can be used to calculate the central tendency in this scale. The only drawback of this scale is that there no pre-decided starting point or a true zero value.

Interval scale contains all the properties of ordinal scale, in addition to which, it offers a calculation of the difference between variables. The main characteristic of this scale is the equidistant difference between objects. All the techniques applicable to nominal and ordinal data analysis are applicable to Interval Data as well. Apart from those techniques, there are a few analysis methods such as descriptive statistics, correlation regression analysis which is extensively for analyzing interval data.

Descriptive statistics is the term given to analysis of numerical data which helps to describe, depict or summarize data in a meaningful manner and it helps in calculation of mean, median, and mode. Ratio Scale is defined as a variable measurement scale that not only produces the order of variables but also makes the difference between variables known along with information on the value of true zero.

It is calculated by assuming that the variables have an option for zero, the difference between the two variables is the same and there is a specific order between the options. With the option of true zero, varied inferential and descriptive analysis techniques can be applied to the variables.
