Grade 4: Probability and Statistics

4.PS.1

The student will apply the data cycle (formulate questions; collect or acquire data; organize and represent data; and analyze data and communicate results) with a focus on line graphs.

4.PS.1.a

Formulate questions that require the collection or acquisition of data.
(Content unavailable)

4.PS.1.b

Determine the data needed to answer a formulated question and collect or acquire existing data (limited to 10 or fewer data points) using various methods (e.g., observations, measurements, experiments).
(Content unavailable)

4.PS.1.c

Organize and represent a data set using line graphs with a title and labeled axes with whole number increments, with and without the use of technology tools.
(Content unavailable)

4.PS.1.d

Analyze data represented in line graphs and communicate results orally and in writing:

4.PS.1.d.i

describe the characteristics of the data represented in a line graph and the data as a whole (e.g., the time period when the temperature increased the most);
(Content unavailable)

4.PS.1.d.ii

identify parts of the data that have special characteristics and explain the meaning of the greatest, the least, or the same (e.g., the highest temperature shows the warmest day);
(Content unavailable)

4.PS.1.d.iii

make inferences about data represented in line graphs;
(Content unavailable)

4.PS.1.d.iv

draw conclusions about the data and make predictions based on the data to answer questions; and
(Content unavailable)

4.PS.1.d.v

solve single-step and multistep addition and subtraction problems using data from line graphs.
(Content unavailable)

4.PS.2

The student will model and determine the probability of an outcome of a simple event.

4.PS.2.a

Describe probability as the degree of likelihood of an outcome occurring using terms such as impossible, unlikely, equally likely, likely, and certain.
(Content unavailable)

4.PS.2.b

Model and determine all possible outcomes of a given simple event where there are no more than 24 possible outcomes, using a variety of manipulatives (e.g., coins, two-sided counters, number cubes, spinners).
(Content unavailable)

4.PS.2.c

Write the probability of a given simple event as a fraction between 0 and 1, where there are no more than 24 possible outcomes.
(Content unavailable)

4.PS.2.d

Determine the likelihood of an event occurring and relate it to its whole number or fractional representation (e.g., impossible or zero; equally likely; certain or one).
(Content unavailable)

4.PS.2.e

Create a model or contextual problem to represent a given probability.
