Differentiate between reliability and validity?

If something is reliable, we trust that it will do the same thing over and over. This could be an engine, or a mathematical model.

If something is valid, we could say it is true, or trustworthy.

Reliability can be seen as concerning a process.

Validity could be seen as the positive outcome of a process.

We can rely on this (mathematical) model to give us valid results.

Or, we can rely on Professor Hawkins to give valid answers to impossible questions.

Reliability refers to the consistency of a measure but Validity refers to the accuracy of a measure it means the results really represent what they are supposed to measure 

Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).

Intro MiaLarson-d9ce5d

Mia Larson

I have a Bachelor of Science degree from the OCAD University,
and TEFL certificate.

We focus on grammar, pronunciation, reading, and other English skills in class.
We have various methods for easy English learning in our class.
In our class, you can ask any question.  
Making mistakes in our class is not a bad thing.
Because we know that it's part of the learning process.
I am very patient, and you can also ask me about topics outside of the lesson.
We teach you  effective methods for memorizing new vocabulary.

Teaching should be fun and relevant. It's important to me that we remained relaxed in sessions, but have an aim an focus. Nearly all of my lesson materials are custom made for my students. This help us make very fast progress.

My CV is a little colourful.

My BA is in Theology, from Kings College, University of London,

My Master is in Film from Middlesex University, also the University of London.

My TEFL120hour Certification, is from TheTEFL.org

For about 15 years I worked in the world of Corporate Communications and Public Relations. This involved a huge amount of research, writing and communicating at a senior level.

But, there were many other jobs along the way - working security through to hotels. 

I've volunteered with young people, the homeless and lots of other things.

In every role, I've happily been the colleague that helps other colleagues (and friends) get that little bit better at what they do.

Dogs, cat, boats and films are probably my biggest hobbies.

Intro DominicBrant-0d934f

Dominic Brant

Based on my Corporate background, I have a huge interest in helping people develop their CVs/Resumes and interview techniques. This becomes more of a mentoring relationship. The essence is to help my clients to both understand and then express their own professional stories in a compelling and meaningful way. I am to give a little light of  hope to the miserable world of job hunting/career development. I have, and do, work with senior staff and leaders - business, academic and NGO.

I've been involved with many local and a few national charities, often focussed on mental well-being and the needs of young people.

If you have any special needs, or are involved in these fields, then I'm extra very happy to work with you!

If you are dyslexic or have particular learning needs you'll get nothing but support from me.

If you're super ambitious and have a plan, then Game On, let's get to work. :)

All language skills over-lap. If you learn grammar to talk about a hobby it's easier to use that same grammar at work, with friends, or your family.

Conversation is a great way to build confidence.  Then we grow to include novels, short stories, articles and journalism. Nothing is out of bounds - as long as it is well written.

When you're ready and willing, you can also write reports and short texts. Here I become your editor: your words, your ideas and my feedback. This is a lot of fun, and you create a portfolio of your own writing!

Whatever you reason to learn, remember that any English you learn is valuable and useful so long as it has a purpose. The vocabulary may change, but the grammar and structures do not.

I look forward to working with your :)

Fun, focussed and relevant. Business. Academic. Creative.
