Students perform single and two-sample t procedures to investigate special cases of normally distributed data. They explore inference for a least-square regression line, including the confidence interval.

Students graph scatter plots and understand the concepts of correlation and least-squares regression. They also perform transformations to achieve linearity in the data plot.

This App brings a new level of simplicity to calculator-based data collection, making data collection simple and fast.

[Free Registration/Login may be required to access all resource tools.] Find the median of large sets of data.

[Free Registration/Login may be required to access all resource tools.] Covers frequency distribution tables with ungrouped data.

Using the USA TODAY Snapshot, "More of U.S.," students will learn how to interpret data presented in a graphical form. Students will determine the rate of change (slope) and build a linear model (y = mx + b) from this data. The model...

Students will determine the mean, median, mode and standard deviation of collected data. They will make a frequency histogram of the grouped data, both on graph paper, and on the TI 83+.

In this activity, students collect population data for the world on 10 different days and then find a model for the data set assuming that over a short period of time the data can be considered linear. Finally, they evaluate the model...

Students examine the USA TODAY Snapshot "More of U.S.", construct a graph from the data, produce a mathematical model (linear) for the data, determine the rate of change for the data, and make predictions about future population levels.

In this activity, students interpret data tables and graphs. They find percentages, and create circle graphs to display data.

In this investigation teams of students will explore variations in measured data. Students will drop an object from the same height 47 times and record the time for each drop.

Students will compare charges from two skate rental shops and, using data from their lists & graphs, determine the conditions required for one shop to be less expensive than the other.

Students will examine the current and predicted population data from the countries included in the USA TODAY Snapshot "Growing bigger by the decade".

In this activity, students test if a significant relationship exists between a bivariate data set, and then calculate the confidence and predictive intervals. They also improve the interval-prediction capabilities by automating the process.

In this activity, students compare their height with the average height of students in the class. They create histograms to analyze the data, and construct box plots to summarize the height statistics.

Students practice with the parameters of the vertex form of the parabola and their effect on the shape of the curve. They use this concept to find a quadratic model. They also use translation and dilation to change the general parabola.

Maleic Acid gives an excellent diprotic acid titration curve showing both inflection points clearly for calculation of molecular weight.

Students learn the conversion relationship between inches and centimeters through data collection. The data collected results from measuring items using inches and centimeters as the units. They use a TI-73 to input the data into lists...

This activity gives students an opportunity to select and create the most appropriate graph to represent a given data set.

In this activity, students' will use a pH sensor to determine the pH of common beverages. They will use the data to create different types of graphs. Students also learn to classify liquids and identify an unknown sample.

Students will create a scatter plot for the data in the USA TODAY Snapshot, "Cropland value grows," and identify the independent and dependent variables for the data. The students will find the rate of change for the data and label this...

Students will create two box-and-whisker plots of the data in the USA TODAY Snapshot, "Super ticket sales". Students will calculate central tendencies for both sets of data. Students will compare the two sets of data by analyzing the...

French fries from your cafeteria to do data analysis. The students count the number of fries in a single serving of fries along with weighing the order, then measure the length and weight of a sample of individual fries. You then use the...

With this resource, students will examine and evaluate data on the corn harvest in the United States over the past several years. Using the USA TODAY Snapshot "2004 corn crop is a bin-buster," data from the USDA Statistics Service...
