Thanks. I found an explanation online that weighted moving averages relate to investing and something about how more recent events being given more weight than past events. I suppose that makes sense...sort of.

I haven't seen a difference between weighted moving average and moving average. They have to be different, but I don't know how.

I have taken statistics classes (more than I have ever wanted to). This never came up. Ever. It doesn't seem to be relevant to statistics, though, only to investments and weight loss. Or maybe it's a more advance concept than most statistics.

I'm going to pass on the Hacker's Diet SparkTeam, as I'm maintaining rather than losing at this time.

Yes, unweighted moving averages can be helpful too.

I believe the reason people like the weighted ones is because they help you spot trends sooner, which means you can correct them sooner.

Never, ever, EVER give up!

Moving averages have been a key tool in my weight-loss program from the beginning. I discuss this in depth in my blog:

It's explained more in the Hacker's Diet. There's a whole team about using weighted moving averages, here:
teams.sparkpeople.com/hackers
diet

If you have questions, that might be the best place to ask them, since most of the people there are using these tools...

The difference between a weighted moving average and a regular moving average of the kind you seem to be describing is that today's weight counts more in the average than yesterday's, which counts more than the one from the day before yesterday. Weighting the recent measurements more heavily helps you see trends sooner.

You can see how it's calculated, here:

If you don't want to bother doing the calculation yourself you can use an online tool like this one:

Hope this helps.

Gee, I had heard of weighted moving average too and it sounded complicated! All I have to do is weigh myself every day, add 7 days together and divide by 7????? Oh my gosh, that's easy!

I'm pretty good at math, and have been doing just what your are, but am interested in knowing more about the whys and hows of this weighted averaging.

I'll admit that math is not my strong suit. So I am having a hard time understanding "weighted moving average" and how it is different from a "mean."

When I calculate a mean, I add all the data I have collected, say, my weight from each of 7 days this week, and divide by the number of items I have (in this case, 7).

Weighted moving average implies something much more complicated, and I don't understand why it needs to be complicated and why we need to go to a special web site in order to figure it out.

Can someone explain?
