There are two main types of variables: categorical and continuous. Categorical variables are those that have discrete categories or levels. Categorical variables can be further defined as nominal, dichotomous, or ordinal. Nominal variables describe categories that do not have a specific order to them.

A diatonic scale is a type of music scale with seven notes (also called a heptonic scale). Diatonic scales must have two semitone intervals (half steps) and five tone intervals (whole steps) within one octave. The two semitone intervals should be separated by two and three tones. What is theRead More →
For ordinal data (individual Likert-scale questions), use non-parametric tests such as Spearman’s correlation or chi-square test for independence. For interval data (overall Likert scale scores), use parametric tests such as Pearson’s r correlation or t-tests. Can I use t-test for ordinal data? T-tests are not appropriate to use with ordinalRead More →
Every major scale has its relative minor, which uses the same notes. This relative minor scale is a natural minor scale, and it starts from the sixth degree of the major scale. This relative minor scale is the Aeolian mode of the major scale. What is an aeolian minor scale?Read More →
U.S. scales will measure 28 grams per ounce, while gold is measured at 31.1 grams per Troy ounce. Some dealers may also use a system of weights called pennyweight (dwt) to measure a Troy ounce, while others will use grams. A pennyweight is the equivalent of 1.555 grams. Is goldRead More →
Matchbox cars are nominally 1:64 scale, but the size of existing similar models, cost and packaging restrictions, ease of production and standard wheel and axle sizes all impact upon the final proportions and scale of the car. Are Hotwheels 1/64 scale? Many diecast automobiles and commercial vehicle models for collectorsRead More →
How do you calculate full scale? By Jon Sanders. … Accuracy as a percentage of reading is accomplished by multiplying the accuracy percentage by the pressure reading. … Figure 1 – Percent reading. … Accuracy as a percentage of full scale is calculated by multiplying the accuracy percentage by theRead More →
Common sliding scale regimens: Long-acting insulin (glargine/detemir or NPH), once or twice a day with short acting insulin (aspart, glulisine, lispro, Regular) before meals and at bedtime. Long-acting insulin (glargine/detemir or NPH), given once a day. What is Humalog classified as? Humalog (insulin lispro) is a fast-acting insulin that controlsRead More →
So seismologists created a new scale, called the moment magnitude scale. The moment magnitude scale captures all the different seismic waves from an earthquake, giving a better idea of the shaking and possible damage. Does the Mercalli scale measure magnitude? An earthquake has one magnitude. The magnitude does not dependRead More →
Ordinal is categorical with ranking where as scale is quantitative. Are scales ordinal or continuous? Categorical and dichotomous usually mean that a scale is nominal. “Continuous” variables are usually those that are ordinal or better. Are rating scales ordinal or nominal? Nominal data collection does not include rating scales, whichRead More →
