An Illustrative Guide to Statistical Power, Alpha, Beta, and Critical Values

From my interactions with undergraduate students, it seems that even though these definitions are easy to recite, they are difficult to be integrated into a comprehensive whole. I hope here to show how to conceptually integrate them into a cohesive picture.

This post was originally created for Psychology in Action, and edited by her new blog master, Tawny Tsui. See her posts here.

Everything begins with reality: the “Reality Continuum”

PowerAlpha1I call this green line “Reality Continuum” (rather grand, no?) because you will take your ideas, and do a reality check against it via data analysis (within the traditional statistical framework–it is definitely NOT the only framework on the market, but I digress).

Amazed to learn…

Amazed to learn…

Speechless, I learnt anew of Your love for me.
_____ Yes, You have told me before,
_____ Grace manifested on the Cross.

(Zephaniah 3, Psalm 147, Luke 15)
You opened my eyes; the Cross means so much more!
_____ You rejoice in me;
_____ You delight over me;
_____ You run to me even before I reached for You;
_____ You dance with joy on the day you ordain to bring me home;
_____ You sing (loudly!) over me!

Who? Me?! Wah…

(Luke 15)
When I repented, it is not the angels who danced,
_____ “There is joy before the angels of God.”
_____ Who is before the angels but the Mighty I AM Himself?
You, Yourself, the Dignified Father, dance with joy to reunite with me!

(Ephesians 1)
I am Your inheritance, as You are mine.
_____ You have longed for me, an eternity before I started longing for You.
You see me as righteous, even as I stumble.
_____ You call me child, even as I cover myself with filth.

(Ephesians 1, Romans 8)
You decided. You will make me like Christ.
_____ You cannot be thwarted, despite of me.
You promised. You will make me like Christ.
_____ You cannot fail, despite of me.

On Christ, Anxiety, and Waiting (in Academia)

More than most of us are willing to admit, the life of an academic and scientist consists of much waiting.

Some do this better than others; I am not, by nature, one of them.

Many times I have been weighted down by the anxiety of waiting: for graduate school acceptance letters, for getting a grant for my research, and for graduate research fellowship funding, etc.

It is now the season of waiting to hearing from graduate schools (the tail end of that), fellowship applications, job search for new graduates, etc. It is lent, too, though I am not of the Catholic tradition.

The following is probably the most personal post I have attempted. I will share how the Holy Spirit ministers to me through the Bible in hopes that it would help minister to you in such seasons. Especially for those of you whom Jesus has called to be a missionary in the scientific fields–the prevalence of Christians in these fields could probably qualify them as unreached people groups! (Perhaps with the exception of physics and mathematics by reputation? But I have no stats, and it is neither here or there.)

These are not trite statements, but came both from seasons of waiting that turned out to be “successful” and “unsuccessful.” Amazing that the Spirit gave me the same comfort prior to both. Humbling too, that He has to do this repeatedly for me [chuckle]. I am the “chief of sinners” and still learning this, repeatedly.

ALIVE featured in “I Love UCLA” video contest entry!

Directed by Andrew Butte, this is an entry for UCLA Fund’s 4th video contest “I Love UCLA.”

@ about 30s in, Daniel Lin, our Undergraduate Project Leader was in the video greeting the view-point character, then the latter explored our UnderSea Campus 😀

Fun stuff.

Odds Are: On the difference between odds, probability, and risk ratio.

Odds, Probability, Chance, Risks: Interchangeable?
Not so much.

What does it mean to say “smokers are X times more likely to get lung cancer than non-smokers?” What about
when the weather channel says, “there is a 10% chance of rain?” The odds of 1 to 10 of winning?

These words are often used in casual conversations as somewhat interchangeable, and can be rather confusing. I remember being very excited to learn about them for the first time, so hopefully you will find this as interesting (or at least as clarifying!) as I did!

A little test!

odds-in-your-favor

In which of the following scenario are you most likely to find dessert happiness? Which ones are saying the same thing?

A. The odds against you eating a cupcake are 1 to 5.

B. Your odds of/on eating a cupcake are 1 to 5.

C. The probability of you eating a cupcake is 20%.

D. You have a 20% chance of eating a cupcake.

Answers, in short: A is the most likely-for-cupcake scenario, and C and D are saying the same thing.
