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.

the perfect outdoor solution & very well priced
Color: Lake Blue
This is a beautiful & sturdy umbrella. i had owned a Pier I multi tiered umbrella ($198) and it looked great when I first brought it home, but after one summer, it had faded, the wood swelled to the point where I couldn't get it out of the stand & when the skeleton arm broke, it could NOT be repaired & I paid more than a few carpenters to try. THIS umbrella is a completely different experience from start to finish: well made, lightweight fabric, easy to unpack & popped right into the stand without tiresome effort: no ladders required. It does exactly what it’s supposed to: protects from hot sun & rain, tilts accordingly & I LOVE the deep teal blue that is very soothing in all weather conditions. The price is affordable and I hope it lasts for years. I’m a VERY happy customer!

Easy to use and seems sturdy
Color: Aqua Blue
It’s perfect! Larger than or last one. Easy to set up. Fits in a standard table hole and base. The color is just what the dogs wanted! Everything is always so grey and dull! The turquoise really pops

No customer service for product under warranty
Color: Beige
loved this umbrella for the 4 months we used it. did a lot of research to find an umbrella that would stand up to New England "breezes" -- this one was advertised as wind resistant; bought in June 2025, seemed very sturdy, really nice-looking, used on our patio (installed in the base the recommended base) through the summer; stored indoors for the winter; brought back onto patio a couple weeks ago. On a day with average wind a couple weeks ago, the tilt mechanism broke. Umbrella did not fall over, a gust of wind just forced the tilt mechanism to snap. Spent a lot of time trying to fix it, but it's permanently broken. It's less than a year old so still under warranty, as stated in the materials they sent with the umbrella. Same materials list the email to contact if there are any problems with the product. Have emailed the company, twice now, asking for a refund or replacement. Radio silence. Don't buy this unless you're ok with throwing it away after four or five months of use and being ignored by customer service.
