Sir Ronald Fisher

represent differences in quantity, character, or kind but not in amount.

Qualitative variables

– are numeric in nature and can be ordered or ranked. • Examples of quantitative variables are weight, height, age, test scores, speed and body temperatures. Quantitative variables are further classified as either discrete or continuous

Quantitative variables

a variable whose values can be counted using integral values such as the number of enrollees, drop outs, graduates in a certain college, deaths, number of employees. Discrete variable assumes integral values.

Discrete variable

a variable that can assume any numerical value over an interval or intervals. Examples include height, weight, temperature, time, pressure in a tire, and a number of miles driven. Continuous variables yield decimal or fraction.

Continuous variable

use numbers for the purpose of identifying name or membership in a group or category. Observations can be classified and counted without a particular order or ranking imposed on the data.

Nominal Data

Number Medical Technologist that are members of PAMET, and schools attended by all Board passers are example of?

Nominal Data

connote ranking or inequalities. One category is higher than the other one. In this type of data, numbers represent “greater than” or “less than” measurements, such as preference rankings. Individuals may be classified according to socioeconomic status as low, medium, or high

Ordinal Data

Primary, Secondary, and Tertiary hospitals in Metro manila, and list of honor students are example of?

Ordinal Data

– indicate an actual amount and there is equal unit of measurement separating each score, specifically equal intervals

Interval Scales

In Celcius and Fahrenheit temperature, a 10° increase in the temperature reflects the same amount of heat, regardless of whether it represents a change from 10° to 20° or a change from 60° to 70° is example of?

Interval Scales

are similar to interval data, but has an absolute zero and multiplies are meaningful. Ratio data include all the usual measurements of length, height, weight, area, volume, density, velocity, money, and duration.

Ratio data

Number of calories per-4ounce portion of ice cream for different brands and size and diameter of a bacteria are example of?

Ratio data

Can be more effective and informative if given the necessary preparation and planning.

Primary data collection

Primary data collection can be collected through the following:

AOTA

Are information taken from published or unpublished materials previously gathered by other researchers or agencies such as books, newspapers, magazine, journals, published and unpublished thesis and dissertations

Secondary data collection

In this type of sampling, we select samples at regular intervals based on sampling fraction. The items or individuals are arranged in some way- perhaps alphabetically or other sort.

Systematic random sampling

In this type of sampling each member of the population has an equal chance to be included in the sample gathered through Lottery or Fishbowl technique. Commonly recommended to prevent bias or erroneous inference

Simple random sampling

In this type of sampling, we select random samples from within homogenous subgroups while being different from each other

Stratified random sampling

This sampling is sometimes referred to as an “area sampling” because it is frequently applied on a geographical basis

Cluster sampling

This is a graphic representation of frequency distribution where adjoined vertical rectangles are drawn on horizontal axis with the centers of the bases located at the class marks

Histogram

A graph that represents class boundaries along the horizontal axis and cumulative frequencies along the vertical axis

Ogive

This is a graph showing the cumulative frequency less than any upper-class boundary plotted against the upper-class boundary.

Less than ogive

This is a graph showing cumulative frequency greater than any lower-class boundary plotted against the lower-class boundary

Greater than ogive

three most important measures of central tendency: the mean, the median, and the mode. Often more simply referred to as “Average”.

Measures of Central Tendency

Deviation and Average is a shorter formula for computing the mean by using this process/method.

Coding or Deviation Method

All are meaning of MEAN except:

It is used with symmetrical, multimodal distributions of interval or ratio scores.

Is defined as the sum of all scores or data divided by the number of scores in the data

ungrouped data

x̄ = Σfx/n

grouped data

All are meaning of MEDIAN except

Used when the research problem calls for knowledge of the exact endpoint of a distribution.

All are meaning of MODE except:

Most frequently reccurring score in the ungrouped data

The difference between the highest/maximum and the lowest/minimum values in the set of data

Range

The most commonly used measures of variability are?

the variance and standard deviation.

Measures the average amount by which each data point in a dataset differs from the mean, providing an indication of the spread or dispersion of the data.

Standard Deviation

A lower standard deviation indicates that the data points are closely clustered around the ____, while a higher standard deviation suggests greater variability or spread in the dataset.

mean

Meaning of Coefficient of Variation

AOTA

It is a term used to mean a statement about one or more parameters of a population or populations

Hypothesis

Symbol represents population mean

It is a procedure consisting of pertinent steps whose major objective is to be able to make a decision based on the data gathered.

Hypothesis Testing

Evaluates evidence from a sample to draw conclusions about a population parameter

Hypothesis Testing

All are meaning of null hypothesis except

NOTA

All are meaning of Skewness except

If the mean is largest of the three averages, the distribution is negatively skewed or skewed to the left., If the mean, median and mode are equal, then there is a skewness

The empirical rule correspond to specific proportions of data falling within particular standard deviation intervals

Probability theory

“The three-sigma rule”

68-95-99.7

To use this statistical test, there are some conditions that should be met. The data must be normally distributed and the level of measurement must either be interval or ratio.

Parametric tests

All are Parametric tests except

x-test

All are Nonparametric tests except

Kruskal-Wallis H-Test

This statistical test does not require normality of the distribution.

Nonparametric tests

t-test typically used when there are fewer than ___ samples.

The t-test formula for related samples used to compare the pretest and posttest mean or the means of two groups.

False

Use to compare population means when determining if one is greater or less than the other.

One-tailed t-test

It is used to compare two means, the sample mean, and the perceived population mean. It is also used to compare the two sample means taken from the same population. It is used when the samples are equal to or greater than 30.

z-test

represents the spread of the data in the standard normal distribution

Standard deviation

used when the sample mean is compared to the perceived mean.

One-Sample Mean test

comparing two separate samples from a normal population, what test is used to determine if the difference between values is significant.

Two-Sample Mean Test

This is the test of the difference between the observed and expected frequencies. This is considered a unique test due to its 3 functions.

THE CHI-SQUARE TEST

Used to compare the medians of two independent samples.

THE WILCOXON RANK-SUM TEST OR WILCOXON TWO SAMPLE TEST

This is a test of difference between the observed frequencies and expected frequencies

CHI-SQUARE TEST OF GOODNESS-OF-FIT

All are Kruskal-Wallis H-Test except

This is used to compare the medians of two independent samples.

Measures the strength and direction of the association between two ranked variables. Does not require the assumption of normality
