Frequency Data and Behavioral Health

Understanding Frequency Data in Behavioral Health and Education


Frequency is one of the simplest and most powerful concepts in behavioral health, education, and basic statistics. It refers to how many times something occurs. 

Frequency is the number of times something occurs for instance; the number of times a student raises their hand in class.

Because frequency is so fundamental, it shows up everywhere: in classrooms, therapy sessions, behavioral observations, and test score analysis. Once you understand how to record and visualize frequency, you gain a clearer picture of patterns, habits, and performance.

Recording Frequencies

Frequencies can be captured in several simple ways:

Tally marks on paper

Counts entered into a spreadsheet

Tables that list an item and how often it occurs

Here's a simple table showing the frequency of four scores

Visualizing Frequency Data

Visual displays make frequency patterns easier to understand at a glance. Your document highlights three classic methods: dot plots, and bar charts.

---

1. Dot Plots

A dot plot places each score on the x axis and stacks dots above it to represent how many times the score occurs. 

Place the scores on the x-axis and place a dot above each score to represent the frequency of the score.

Dot Plot










This makes dot plots ideal for small datasets.

2. Bar Charts (Column Charts)

Bar charts use vertical columns to show frequency. The height of each column corresponds to how often a score appears. This is especially helpful when comparing categories side by side.

The height of a column represents the frequency of each score as indicated by the numbers on the y-axis.

Why Frequency Visualizations Matter


Frequency charts help instructors, clinicians, and researchers:

  Spot patterns quickly

  Compare behaviors or scores

  Identify outliers

  Communicate findings clearly

  Make data intuitive for students or clients

  They also reinforce a foundational statistical principle:


Note

In a statistical chart or graph, the x-axis is horizontal and the y-axis is vertical

Academic Self-Efficacy Scale ASE

  Overview The  Academic Self-Efficacy Scale is an application of Self-Efficacy Theory   to examine the relationship between self-efficacy and academic performance using 8-items rated on a 7-point scale. The work of Chemers et al. (2001) has been widely cited. Format The 8-items are rated on a 7-point Likert-type scale ranging from 1 = Very Untrue to 7 = Very True. Sample Items 2. I know how to take notes. 6. I usually do very well in school and at academic tasks.   Reliability, Validity, and Other Research notes In the article describing the development and use of the ASE, the authors observed: “As predicted, academic self-efficacy was significantly and directly related to academic expectations and academic performance.” (Chemers et al., 2001, p. 61)   Sutton et al. (2011) reported Cronbach's alpha of .83 in their study of academic self-esteem and personal strengths. ASE was highly positively correlated with ACT scores (.24) and GPA (.39)....

Brief Self-Control Scale (BSCS)

  Assessment name:   Brief Self-Control Scale Scale overview: The Brief Self-Control Scale (BSCS) is a 13-item self-report measure of self-control, which is also called self-discipline and willpower.   Authors: June P. Tangney, Roy F. Baumeister, Angie L. Boone   Response Type: Items are rated on a five-point scale of self-evaluation from 1 = not at all like me to 5 = very much like me. Scale items Example items include “I am good at resisting temptation” and “I have a hard time breaking bad habits” (reverse coded). Psychometric properties In their original publication, Tangney and others (2004) documented high internal consistency and retest values. High scores representing self-control were associated with academic success and better relationships whereas low scores were correlated with personal problems and problem relationships. Availability: The BSCS is widely used and available in many languages. The original 36-item scale and the Brief...

Rotterdam Emotional Intelligence Scale (REIS)

  Scale name: Rotterdam Emotional Intelligence Scale (REIS) Scales overview : The Rotterdam Emotional Intelligence Scale (REIS) is a 28-item measure of emotional intelligence having four subscales. Authors: Pekaar, Keri A., Bakker, Arnold B., van der Linden, Dimitri, & Born, Marise Ph. Response Type: All items are rated on a 5-point Likert type scale ranging from 1 (totally disagree to 5 (totally agree). Subscales = 4   Following are the four subscales with a sample item. Self-focused emotion appraisal( 1. I always know how I feel.) Other-focused emotion appraisal ( 8. I am aware of the emotions of the people around me.) Self-focused emotion regulation ( 15. I am in control of my own emotions.) Other-focused emotion regulation ( 22.

The REIS was strongly correl...
