Professional Development Presentation: Descriptive Statistics

Understanding measurement principles and the characteristics of assessments helps to minimize bias in individual teacher assessment practices.

Explain descriptive statistics encouraging deeper understanding of how data is derived to aid decision-making within the classroom setting.

Create a digital presentation, to be used for professional development, which creatively and accurately explains the dimensions of descriptive statistics. Your presentation should be 10-15 slides, including a title slide, reference slide, and presenter’s notes.

Within your presentation, explain each of the following:

Reliability
Validity
Bell curve
Mean
Standard deviation
Standard scores
Scaled scores
T-Scores
Percentiles
Conclude your presentation by describing how this knowledge relates to data literacy and why it is important for teachers to understand it when making educational decisions and differentiated instruction for individual students, including those with disabilities.
