Math Mammoth Statistics & Probability is a worktext covering statistics and probability topics for grades 6 and 7 Being a worktext, the book contains BOTH the instructions and exercises.

The statistics lessons in the first section are for about 6th grade level, starting with the lesson Understanding Distributions. The concept of distribution is a fundamental theme in the study of statistics, and is basically how the data is distributed. The distribution can be described by its center, spread, and overall shape.

Two major concepts when summarizing and analyzing distributions are its center and its variability. First we
study the center, in the lessons about mean, median, and mode. Students not only learn to calculate these values, but also relate the choice of measures of center to the shape of the data distribution and the type of data.

Next, we study measures of variation, starting with range and interquartile range. Students use these measures in the following lesson, as they both read and draw boxplots.

The lesson Mean Absolute Deviation introduces students to this measure of variation. It takes many calculations,
and the lesson gives instructions on how to calculate it using a spreadsheet program.

Next, students learn to make histograms. They will also continue summarizing distributions by describing their
shape, and giving a measure of center and a measure of variability.

The next focus area of the book is random sampling. Students learn that sampling methods vary and that random sampling is likely to produce an unbiased sample. Students will also practice making inferences about populations based on several random samples.

Another major topic is comparing two populations, either directly or by using samples from the populations. Students learn to use the overall distributions and the measures of center and variability to compare two sets of data in various ways.

The next section deals with probability. We start with the concept of simple (classic) probability. Students calculate probabilities that involve common experiments, to include flipping a coin, tossing dice, picking marbles, and spinning a spinner.

In the next lesson, Experimental Probability, students conduct experiments, record the outcomes, and calculate both the theoretical and experimental probabilities of events, in order to compare the two. They will draw a card from a deck or roll a die hundreds of times.

Lastly, we study simulations and the probability of compound events.

Hallelujah!
My hands were so dry and cracked until I got these babies. I didn't realize what I was getting myself into and was surprised when they were lined with some kind of silicone. Night one, I lathered my hands with whatever lotion I had laying around and went to bed. Now, these gloves are not super comfy because they're so thick, but not so bad that I won't use them. Anyway, wore them several hours and took them off in the middle of the night (they recommend at least 20-30 minutes). In the morning, my hands were baby soft. No cracks. No dryness in sight. AND it lasted all day. I did it the night after and I have not had dry hands for nearly 2 weeks! It's insane. I'm SO happy. Definitely worth it as a little treat yourself.

Bulky
I was a little disappointed in how bulky these were and seemed hard to get on. If you can get past this they do seem to work good. Hands do seem softer and a bit healthier.

Really moisturizes hands
These gloves really work. My cuticles and hands alway seem dry. I used these gloves the first night I received them and my hands were really smooth afterward. When I get in bed at night, I play on my computer and iPad, and these gloves are perfect. The end of the index finger is designed to be used with a phone, computer, and iPad. Make sure you push the end of the fingers on the gloves all the way down to the end of your fingertips; otherwise you will not be able to use them with a device. I find they work better with my iPad than my computer. I have not tried to use with my phone. The gloves are not uncomfortable, but I found they are not comfortable to wear all night, so I just try to wear them about an hour every night. I wish I had these gloves about 20 years ago and my hands would probably look like a 20 year old.

So much pain
I had to remove these after less than 5 minutes as they caused such intense pain. The gel clings to your skin even with the lotion and tightens around your hands cutting off circulation. They have been off for about half an hour and my hands still hurt. I was so excited as I really like this brand in general. Very disappointed. Be very aware when buying.

Moisturizing Gloves That Actually Work
Over the years, I have tried so many different types of gloves to alleviate my dry skin. Since it especially bad on my hands I have tried everything. Of all the gloves I have purchased, this pair is head and shoulders above all the others. The first night I used these I could not believe the difference! It was astonishing. My hands were soft and supple for the first time in my life, and they stayed that way for most of the day. The moisturizing aspects of leaving humectants on one's skin for prolonged periods is really a game changer. They fit perfectly and can be pulled on with ease. The crazy bonus is that I was still able to use my phone once I was wearing them. That has never been the case with any of the other gloves I've used. If you have dry skin on your hands, you must try these. One night of use and you will be sold!
